CFC3 in Bogota, Part II

The conference started on a Friday so we flew down on a Thursday.  As a very tall person, I can’t fly coach on long flights, so it’s been a lifelong side quest to get upgrades on our seats.  This time we got full-on first class because the price was pretty reasonable.  I can’t stand the whole process of going thru airports and security and everything, it’s all very stressful.  But as a perk we got to go into the sky lounge and chill while we waited for our flight with a nice free lunch and well-stocked bar to take the edge off one’s anxiety.  As I mentioned I was up late the night before working on my presentation, so I slept on the flight.  Flying to Bogota from New York is about that same time and distance as California or western Europe, but in a perpendicular dimension.  It was strange getting off the plane and the time zone *not* to have shifted.  Instead we had travelled almost due south, and we just a few degrees from the equator.

Getting thru immigration was smooth and fast, and the cab ride to our hotel too.  Bogota is a big city, around eight million people, about the same as New York City.  Getting around by taxis and buses was fine.  It’s also at almost 9,000 feet elevation, which you tended to notice after going up a few flights of stairs, at least the first couple of days.

Our hotel was a youth hostel next door to the main conference hotel.  It had a fun, friendly and funky vibe, with a restaurant and bar in the lobby full of reggae and salsa music, and the cheerful comings and goings of backpacking twentysomething gringos alone or in small groups.

Some of our friends had already arrived, and we took a cab to meet them at a bar in the neighborhood.  When we got out of the cab I wasn’t sure I was in the right place, but I heard my friend Matt, who had come outside to meet me, call me name.  Matt is originally from Connecticut, but has lived in Mexico for ten or fifteen years, and so is fluent in both English and Spanish, as were a good fraction of the group.  Ilan, an Israeli and the conference organizer was there, and a handful of people from the local origami group, who were happy to tell us what’s good on the menu and anything else we wanted to know.  At the end of the night we decided to walk back to the hotel with our local guides.  It seemed as safe as New York or any other big city.

Friday morning we had a really good breakfast at the hotel, with eggs and sausage and some kind of cornmeal muffin, and fresh juice (jugo) and amazing coffee.  

The conference was Bogota Universidad, a short walk from the hotel.  Walking around the neighborhood helped us get oriented.   Our hotel was situated right at the eastern edge of the city, and the university campus wound up into the foothills.  Very charming.  The conference itself was at the Japan Center, and the first order of business was to set up my exhibit for the exhibition.  Since my talk was on single-sheet polyhedra, I brought along a number of this.  Also some animals, insects and spaceships.

The talks covered an interesting variety of topics.  There was one on indigenous papermaking in Mexico, another was a panel discussion on how to make it as professional origami artist, another on what is art, anyway? and another on one artist’s specific system of tessellations.  One thing I found interesting was that, in contrast to European conferences where English tends to be the Lingua Franca, everything here was bilingual.  A number of the speakers presented in Spanish and someone translated into English; others presented in English with a Spanish translator.  Some presenters fluent in both languages presented first in one then repeated their speech in the other.  This was actually great for improving my comprehension of Spanish.

These conferences tend to be pretty social and for lunch we walked down to the hill to the edge of the campus where there was a square with a bunch of restaurants.  Along the way we happened to stop in front of a stationary store and I bought a wooden pencil.  I had brought one with me but it rolled under the seat of the plane as we were landing.  I’ve found a dull pencil works best for marking up a sheet of paper on the reverse side while prefolding, since it won’t leave a mark on the side of the paper that shows.  As typically happens at origami conventions, I had a bunch of new ideas for things I wanted to fold.  Lunch was hamburguesas con queso azul o americano, most excellent.

I gave my talk at the end of the first day, and it went over extremely well.  I think most people were not aware of the single-sheet polyhedron technique, and were blown away by the great results one can achieve with it, including stellated, sunken and dimpled forms, color-changes and combining tessellations with polyhedra.  I was super impressed with Jorge, my translator, for conjuring technical mathematical terms such as dodecaedro estrellado.

At the end of the day it was happy hour in Bogota, and the walk back the hotel was full of drum circles, pan flutes and guitars, and street vendors of food and drink.  That night was the conference banquet at the hotel.  The meal featured a thick tasty soup and a variety of meats.  Of course everyone pulled out their packs of paper and started folding and showing one another the things they were working on.

The second day started with another fine breakfast, then a pleasant walk up the hill to the Japan Center and more talks.  To honest I can’t remember what they all were, but it was a good mix of art, commerce, deep dives into various technical and aesthetic aspects of origami design, roundtable discussions, and the like.  I remember in one panel saying how modernism is over a hundred years old and it’s time to move past that and embrace all forms, high and low from every corner, and the 21st century pop art can be seen as the new global folk art.  That seemed to resonate.  I also learned that empanadas stuffed with egg, sausage and beans is the ultimate lunchtime power food.

In the afternoon we took a bus uptown into the suburbs, to the French school, where the local folder’s group was holding their weekly meetup, and we were to join forces in a one-day mini convention.  There was a break in the early evening, and Jeannie and I decided we needed some more cash for the remainder of the trip.  A 50,000 peso note (styled $50.000 down there) is like their twenty-dollar bill, although it’s worth closer to $10 US.  Even though the neighborhood looked pretty posh, they’d warned us gringos not to wander around at night, just in case.  With Jorge as our guide a small troupe of us set out and ended up at the local supermercado.  I was amazed at the variety of fresh fruits I didn’t even recognize, although some seemed in the family of pineapples, mangoes and papayas.  In addition to getting cash, everyone got some random thing.  Jared got a bottle of rum, and the Polish couple got some Pepsis.  

Back at the French school, we did a group activity folding a Jet chocolate wrapper.  The wrapper comes with a mini-poster of something Colombian, often an animal, and the challenge is to fold what’s depicted.  Mine was a dish of food, a sort of stew of meat and potatoes and corn, and I was told it was a local peasant dish, very popular.  After doing a little research, I was already almost of out time, so I decided to try and fold a beet.  I didn’t win any prize.

They had dinner (hamberguasas y empanadas) and drinks at the venue.  A beer was like fifty cents.  Hola!  Amazing how the same basic palette of ingredients scales from street carts to fine dining.  

Before the convention Jorge had reached out to me about learning to fold my Stellated Octahedron with Color Change.  I had time to look up the crease pattern, but I’d never made diagrams.  So together we puzzled it out, and I’m amazed he hung in there and did a decent job at a very complex model.  After that I went around socializing a learning other people’s models. It’s amazing that, for me at least, face-to-face teaching is still the best way of communicating origami ideas, even in this twenty-first century age of telecommunication.  Part of it is that folding is tactile as well as visual.  In another group activity, people stood up and briefly explained a favorite paper of theirs, and what kind of folding it’s good for.  That’s interesting to listen to, but you don’t know anything until they pass a sheet around and can touch and bend it.

My friend Matt accompanied us on the cab ride back to the hotel, which was good since he had an account for whatever their uber is down there, and speaks Spanish.  He made small talk with the driver the whole trip.  I contributed a random phrase here and there like, “Si, yo soy un hombre muy grande.”

CFC3 in Bogota, Part I

You might be wondering if I’ve forgotten about my blog, since it’s been a while since I’ve posted and update.  But I have a good reason.  I’ve been off traveling and adventuring.

I just got back from an amazing trip to South America, and an international origami conference.  The conference was CFC3, in Bogota, Colombia.  CFC is short for Conference for Creators, and as the name implies, is an international organization for origami artists and creators.

At first I wasn’t sure I wanted to go.  I’d never been to South America before, and it seemed like a big leap.  Plus I don’t really know alot of Spanish.  And the US state department even has a warning against traveling to Colombia.

In the end it all worked out and I’m really glad we went.  The conference was fantastic, the people were really friendly, Bogota is a great city and Colombia a really cool country.  The food the music and everything was tons of fun.

I decided if I was going to accept the invitation to go, I should give a presentation.  I chose for my topic Single-Sheet Polyhedra in Origami.  This is an area where I have done a good amount of deep, original work, and I don’t see alot of other folders using this technique.  Indeed alot of origami people mistake my polyhedra for modulars!  It was time to raise awareness.

Here’s a link to the slides for my presentation: zingman.com/origami/cfc3/singlesheetpolyhedra_jszinger.pdf

More on that at later in the story.  For now, suffice to say I was up late several nights in a row the days before we departed.  I put the outline of the talk together in an evening.  The text is mostly prompts, since I detest when people read their slides, and I knew pretty much what I wanted to say.  The thing that took forever was getting together all the photographs and crease patterns.  I spent a couple evenings gathering together models and taking pictures, then cropping and color/contrast balancing them.  I’m glad I bought a new phone with a better camera last fall, it made the whole process more convenient.

The other thing I did was study Spanish for a month using Duolingo, which is a great app.  I’m no great Spanish speaker, but I’d describe my level as “tourist functional”, i.e. I can manage airports, taxicabs, hotels and restaurants, and a bit of small talk.  I’ve studied German, French and Hungarian for other trips, and Spanish felt surprisingly easy.  I guess cuz it’s pretty close to English, and I’ve been hearing it all my life anyway.  

The only thing I wish is that we could’ve linked the trip up with a few days on the beach in a place like Aruba, but it turns out that while we were able to get convenient and affordable flights from New York to Bogota and back, getting around Colombia is not as easy because the country is very mountainous.  We couldn’t hook up anything without major expense, layovers and detours.  Ah well.

Going Down

Today is the fifth Monday of January, almost certainly no one’s favorite day of the year.  I’ve been trying to shake the doldrums of winter.  Lots of rainy and sunless days. Work has been busy and my increasing load of meetings and random tasks means less time to focus on writing software. Michelle went back up to school yesterday, so the nest is empty once again.

Guess what, I’m in a D&D campaign again!  Our last one ended over a year ago when Michelle went off to college.  Last week out of the blue my friend Mark H. up in the Adirondacks asked me if I wanted to join his group.  So I came up with a few ideas for characters, all of them different kinds of fighter/magic-user combinations.  One was Fingongolfinger, an elvish fighter/wizard, an attempt to re-create the classic elf type from the original D&D game.  Fights with a sword and longbow, and casts spells like fireball and lightning bolt.  But the party already had and elvish wizard.  The second was Hiro Ünliikli, a Dragonborn barbarian/sorcerer. This would’ve been pretty wild and weird, but the party already had Teifling, which was weird enough.

The one they liked the best was Grimli Son of Groin, a dwarvish cleric whose deity is Thor.  He fights with a magic warhammer and axe and shield, and has spells like spiritual weapon, and other spell to boost his and party’s fight ability, endurance, and resistance.  He started at level seven and the DM gave him a bunch of cool magic items.  I’m very stoked.

We had our first session last week, over zoom, and I met the party, Mark’s friends, and the whole thing was fun and easygoing. They’ve been playing long enough to have their own tone and rhythm and in-jokes.  I came at a time when they were choosing where to go for the next major adventure, so there was alot of roleplaying and backstory, but no actual combat.  

Only problem is the group meets on Wednesdays, which is the night of my rehearsal jazz group. As luck would have it that was cancelled last week and again this week.  I’ve been thinking of leaving anyway since the group isn’t all that good.  It’s more like going to the gym for sax playing and improvisation over real book tunes than anything else.  But I kinda wanna find a new and better group to replace it.  I’ve been thinking of signing up for a jazz workshop in the city to maybe meet some new and better players.

Happily Spacecats, which rehearses on Thursday, is still fun and creative and sounding better than ever.  My new song Los Gatos de Cosmos, is developing nicely.  But I feel like we need to find some gigs.

In other news, they finally got some snow upstate, so on Saturday we went skiing for the first time this season.  Good to spend time outside doing something physical and get away from staring at the computer screen.  If you recall I took seven years off from skiing, and started again two seasons ago.  At the time I bought new boots and demoed skis on the mountain.  Last year we went skiing three times, up from one the year before.  This year we’re hoping to beat that.

I demoed skis last year but didn’t like them that much.  They were a little short, and while they were very maneuverable, they weren’t so fast on the straightaways.  This year the skis I got are longer, they’re stiffer and lighter than my old skis, and very controllable on different conditions, ice, powder, etc.  But they’re actually close to the length of my old ones.  I’m thinking maybe 5cm shorter would be perfect.

Anyway it was a great day skiing, and we did sixteen runs, which is good amount more then our first trip last year, when we did ten runs.  Michelle is way faster then Jeannie and me now, and just zips right down the mountain. Jeannie and I are thinking of taking a weekend up to the Adirondacks of Vermont or something in a few weeks. 

Don’t Ask Me Why

It’s January.  The darkest darkness has passed, and days are getting longer again.  At five o’clock there’s still some daylight.  We’ve had alot of rainy and overcast days too since the new year.  Up in Buffalo all the snow from the big Christmas blizzard has melted.  It’s been colder here again recently, and we even had a snow flurry or two over the weekend, which puts me in the mind of skiing.

Of course with the holidays over it’s back to work.  Things are off to a good start with both my main gig and The Global Jukebox, moving to grand strategy to operational tactics to writing and and deploying code.

With Michelle home on winter break for another couple weeks, we’ve been playing lots of board games, and as is tradition, watched entire extended edition of Peter Jackson’s Lord of the Rings, about four lads from Liverpool, er, The Shire, who have come into possession of a ring they want to get rid of, while singing songs and being chased by bad guys all over the world, er, Middle Earth to the Bahamas, er, Mordor.

Lizzy came for a visit last weekend, since she didn’t make it home at Christmastime.  We all had a fun weekend which started with going to Billy Joel at the Garden Friday night.  He still puts on a great show, has a great band, and does a fantastic job of mixing up the set list and keeping things fresh.  This night his band did two songs by Jeff Beck, including a stirring rendition of People Get Ready and an impromptu jam of I’m Going Down after the last encore.

The next night we went out to Long Island to Mary and her family, since we didn’t see them at all over the holidays.  We went to Benihana for fancy cook-at-the-table hibachi seafood, which was most excellent.  Haven’t been to one of those in years.  Sunday we watched the Bills game.  They made the playoffs and one the first round.  Two more to go to get to the Super Bowl.

I printed out a bunch of lead sheets for some Billy Joel songs to practice on piano.  Surprisingly, these can take some time to prepare, since chords found on the internet are often not accurate, and the charts always need formatting.  I want the song to fit on one page from start to finish and be as clearly readable as possible.

Lots more going on with music, origami, and other creative and artistic endeavors, but it’s all a work in progress right now.  Will share when the time is right.

Wear Your Blizzard Season Coat

We’re coming to the end of another holiday season.  This one was strangely both eventful and uneventful. I guess I should rewind to the week before Christmas.  Michelle came home from college for winter break, but even though we were no longer symptomatic, Jeannie was still testing positive for Covid, so we all kinda did your best to avoid each other for a few days just in case.  Luckily Michelle never got sick.

We had planned a trip up to Buffalo to visit Lizzy and my parents.  Since she had to work both Christmas Eve and Boxing Day, Lizzy wasn’t coming home, so we figured we’d go up for Xmas day this year.  Our original plan was to drive up on the 23rd and catch the Sabres playing that night.  But then there came talk of a coming blizzard.  When they cancelled the hockey game, we figured it was gonna be trouble.

So we stayed home while the storm slammed into town on the 23rd and continued thru Xmas Eve and subsided sometime Xmas day.  It turned out to be a once-in-fifty-years level storm.  We kept in close contact with Lizzy and my folks, and they were all alright.  My folks just hunkered down and waited it out, and fortunately did not loose power.  Lizzy was at work early Friday morning, but closed her store around nine and left for her roommate’s parents’ house in Arcade, away from the lake effect snow belt.  Made it out just in time.

By mid-morning there was a travel ban in the City of Buffalo and all of Erie county.  All our loved ones were safe, so we decided to stay local for Xmas since.  It was actually really nice to have a couple days of down time with no immediate responsibilities.  I worked out and made more progress on my song, and we all played games and watched movies.

We were going to go over to Mary’s Xmas day, but then Lou got Covid, so that was out.  On Xmas Eve Jeannie went out and got a nice rib roast to cook, and her parents came over, so Xmas was low key but fun.  And everyone got Legos.

We headed up to Buffalo on Monday, boxing day.  The travel ban was still in effect for the city, but in the suburbs where my parents are it was okay to drive.  Once we got past East Aurora the amount of snow on the ground increased considerably.  My folks had a good three feet.  Luckily my dad has a giant snow thrower, and they have a friendly neighbor with a plow.

Lizzy couldn’t go home, so she went to my parents’ too.  And Martin showed up with his family.  We spent two days merrymaking, which was most excellent.  On Tuesday Lizzy took a ride to her store just to make sure everything was okay, and snow was still falling.  I tagged along because I wanted to give my old pair of skis and boots to my friend Larry, who lived nearby. Unfortunately, Larry came down with Covid as well, so I just left them on his front porch instead of going in to hang out.  Ah well.  On Wednesday it finally stopped snowing.  We had thought about going skiing but everyone was too tired.  We ran a bunch of errands in the morning then headed home.

I guess we really needed to catch up on our rest cuz the next day everyone slept in until noon. The last few days we’ve been on a fairly leisurely schedule.   Been trying to go for a walk in the brief, thin daylight every day.  More working out, music, games and movies.  Our New Year’s Eve plans were a bust too since our friends had Covid. 

Ah well back to work tomorrow.

In the Purple Circus

It’s been a few weeks since my last post.  Been busy with work, trying to wrap things up for the end of year, mainly lots of meetings with partners and stakeholders, a few key software commits, and lots of planning and strategy to set up the coming year of projects for our new R&D lab.  Plus, it’s been cold and dark and my energy level has been low.  On top of that I fell Ill with the covid a couple weeks ago, and so did Jeannie. Totally on brand for this time of year.  We’re all better now, but we didn’t get much done beyond the bare minimum for a little while.  We did manage to do most of our holiday stuff.  We put up a lovely tree, and new holiday lights outside, and wrote our Christmas cards, and got a fair chunk of gifts.  Been reading alot, and we watched alot of movies.  Among the better ones was the new production of Dune, although it only covers the first half of the book.

I’ve also been working on a new song in this season of darkness, called ‘In the Purple Circus’.  I wrote the lyric a while back, and earlier this fall set down at the piano and came up with pretty much the entire song, the main riff, the chords, the overall structure and various sections, pretty much all in one sitting.  (Actually also I wrote a song ‘Los Gatos de la Cosmos’ for my jazz group Spacecats around the same time.  It’s a nice little samba based on the harmony of a minor-major-seventh chord, and nice atmospheric spacy jam section in the middle.  It started as an attempt to get inside the head of Jobim, but owes more to Nica’s Dream by Horace Silver, and ended up taking on a direction of its own. More on that once we get the tune together.)

In the Purple Circus is in E minor (from a certain point of view) and the vibe emerged as dark, proggy and heavy. The main riff is in 13/8 time with a couple extra beats on the end after four repetitions so the complete phrase fills seven bars of 4/4 time.  This made it much easier to sequence in ProTools.  The riff uses a downward harmony thing, starting on a Dorian minor, moving to the half-diminished, then the suspended 4th and landing on a #9 dominant 7 chord.  Lots of buzzy tritones and semitones rubbing against one another.  The verse and bridge continue the rhythmic and harmonic motifs.  The time goes to straight 4, but there’s an overlaid 3-against-4 feel, with the downward harmony moving around, and the phrases work out to seven bars throughout.  Then there’s a middle section which takes the main riff and breaks it down, brings it down to a whisper, and builds it back up into a monstrous sonic maelstrom. 

The piano track went down first, then midi drums.  It was starting to take shape with some real character.  Next was bass guitar, which features heavy use of chording on the top two strings while an open E rings out on the bottom.  That sounded pretty badass.  A low E is about 40 Hz.   Having seen Steve Hackett earlier this year, I was inspired by his prodigious use of Moog Taurus pedals to bring the really deep bass.  So I created a bass synth part, an octave below the bass guitar to really emphasize the E-ness on that 20hz tone.  This is right about at the lower limit of human hearing, to say nothing of the frequency response of one’s speakers.  Even on my high-quality but normal studio monitors it sounds pretty great.  I’d love to get a massive subwoofer and hook it into the system.

Next came the electric guitar.  For this record my goal is to put guitar on all the songs, and to develop an approach and guitar part for each song.  For this one the sound was a pretty full and distorted, and I worked out chord voicings both low and high in the range using open strings where I could, to bring out the dissonance and resonance.  I laid down the part and it was just overwhelming!  So now I’m rethinking both the guitar and bass parts to have a bit more space and interplay, to fit together as if they’re the left and right hand parts of some giant 10-string meta instrument.  And to practice the parts so I can lay them down tighter, with particular attention going to the jam/riff bits at the end of the phrases where it builds up over a B altered chord.

So the song is about halfway tracked, and I expect to finish it sometime in the new year, and it will be pretty killer.  Meanwhile, here are the lyrics.

In the Purple Circus
By John Szinger

Well I said, get that bidniz done by Christmas
But the Devil had his plan
So let’s get it thru here by the New Year
Can I talk to the weather man?

The purple circus is where the work is
Vanilla villain where you been?
Chances and changes, chases and cages
I don’t know where to begin

We traffic in majick
Grapple the facets
Conjure abjure and summon
Divination evocation
The mountain surely is a-comin’

She tells me you have the energy of a major enemy
Thick in the grip of crippling sickness n’all
So I vault into the firmament of the permanent tournament
Cuz after all we’re born to crawl

We’ll depart our hostess ‘ere the solstice
Alight beneath the new snow moon
We can check that box off by the equinox
But the lion in roars a day too soon

We traffic in majick
Package the tragic
Sensing seeing knowing
Equivocation declamation
The mountain surely is a-goin’

We traffic in majick, yeah traffic in majick
Yeah, can I talk to the weather man?
Chances and changes, chases and cages, woah
I don’t know where to begin
First there is a mountain then there is no mountain then there is
She’ll be comin’ round that mountain when she comes, yeah

Shine a Light

It’s been another busy couple of weeks.  A week ago, Buffalo NY, where alot of my family lives, got a once-in-ten-years level snowstorm, with my parents in Orchard Park getting six feet of snow.  Up in Amherst they only got a foot or so, but it complicated plans for people coming home for Thanksgiving, especially for my niece and nephew whose trains got cancelled.

In the end, everyone made it home safe and sound, and we had a very enjoyable Thanksgiving. We hosted seventeen people and Jeannie made a most excellent stuffed turkey dinner.  Spent the rest of the weekend listening to music, mainly classic live albums, and playing games like Ticket to Ride and Quirkle with Lizzy and Michelle.

I also finished some home improvement projects.  The big one was was to replace the light fixture in our kitchen ceiling, which blew out right around the end of the summer.  It was an old florescent light in the form of a square wooden box with plexiglas diffuser.  It first I I investigated the possibility of replacing just the socket and electric components.  Once it became clear that wouldn’t work, the quest for a new lamp became a full-blown research project.  We finally settled on one we liked, a broad, shallow frosted glass dome with traditional light sockets that could take modern LED bulbs.  We ordered from a local showroom, but it took several weeks to arrive, and by that I was folding like a madman in preparation for our origami conventions.

Back home again a couple weeks later, I pulled off the old fixture.  I had planned on having to paint the area that had covered because the new light is smaller.  What I didn’t count on was that the old fixture was screwed directly to the ceiling, and there was just a hole where the cup for the wiring and structural support was supposed to be.  So I had to cut a hole in the drywall, buy and install the mounting hardware to the framing of the house, put back the drywall pieces, fill in the gaps, and sand and paint it.  This added considerable time to the job, especially since the ceiling needed two coats of paint.  I ended up finally installing the new lamp Thanksgiving morning, with Jeannie urging me along so we could switch the power back on in the kitchen and she could put the turkey in the oven!

I didn’t quite match the ceiling paint, but it’s pretty close. Lizzy, who works for Sherwin Williams, was very helpful in recommending a mini roller and pan kit; I din’t know they made such a thing.  She also gave me a deck of all their color chips, so hopefully I can do a better job matching next time.

Oh, and, the week before Thanksgiving was a big one for milestones at the Innovation Lab at Consumer Reports.  Here are a couple of press releases about two projects of mine.

Origami Spiders, OrigaMIT and OUSA Holiday Tree

Busy times continue.  The week after the CoCon origami convention in Chicago was OrigaMIT.  This of course is MIT’s origami convention up in Boston, and one of the funnest ones out there, because of the size, venue, general vibe, and emphasis on origami math and theory in addition to the usual teaching models and exhibition.  And also the crowd it attracts. They haven’t had one for three years, so it’s good to be back.  I saw a bunch of origami friends I hadn’t seen in a while.

I largely reused my exhibit from Chicago.  And I taught two of the same models as in Cocon, and they were well received.  Brian Chan gave an excellent talk on how he’s using various CAD software to model constraints, which helps him come up with some very advanced and artistic crease patterns.  His new Scorpion in particular is just mind-blowing.

I ended up spending most of the evening with Beth, Brian and Adrienne, it’s just invaluable to be able to getting into deep conversations with other folders at the level.  In Chicago I started designing a new spider, which I’m calling Hallowe’en Spider.  It’s inspired by some of those classic models with multiple sunken preliminary bases grafted together, but the overall technique is more modern and well integrated.  The goal was a detailed, quasi-realistic looking spider with a fairly straightforward geometry that can be folded in half an hour or so.  I also wanted nice fat legs to make is scarier.

I came pretty close.  There’s not alot of steps, but one of them is a fairly complex sink that’s repeated four times.  At one point Saturday night I was showing Beth what I was up to, and explaining how I needed to adjust the proportions and what were some of my options.  She said, “why don’t you just pleat right here?”, and that turned out to be just the thing.

Over the next few days I finished a few more models, continuing to refine it. I folded a pair of large spiders out of 15″ paper.  One of them is for the American Museum of Natural History’s origami holiday tree.  I haven’t contributed to this in a few years, but this year the them was World of Bugs, so how could I resist?  In addition to the Spider, I folded one of my butterflies and one of my inchworms, also out of large paper.

Meanwhile back home, it’s peak leaf raking season the last couple weeks, with a couple more weeks to go.  And I finally got around to trying to replace the busted ceiling light in my kitchen with a new one I bought back in September, but was on backorder and finally arrived.  However, when I took out the old fixture I discovered it had been screwed directly to the ceiling and there was no electrical cup to hold the weight and connect to mounting hardware to for the new lamp.  So now I gotta cut a hole in the ceiling, install a cup, patch up the drywall, sand and paint it, and then I’ll be able to go ahead and install the new light fixture.  Ah, good times.

Global Jukebox Plos One Article

Over at my other project as lead software developer on The Global Jukebox, I’m happy to announce our article in the peer reviewed journal Plos One has been published:

Chicago Part II – A Hit by Varèse

COCon, the Chicago Origami Convention, was in the downstairs of the hotel, where they had a reception area and series of conference rooms, adjoining the lobby via a broad spiral stair.  It was a perfect setup.  There were a handful of vendors including a friendly woman named Katy who made tiny origami art pieces composed and arranged in little glass bell jars.  Being from Chicago, she gave us great advice on places to eat.

There were ten or so artists exhibiting, so I got a whole table.  My whole exhibit fit in a shoe box in my carry-on luggage, so that was plenty of space.  There were a bunch of my “greatest hits” models, including a turtle, lizard, moose, elephant, dragon, flying saucer and retro rocket.  Also the models I taught: the Space Cat, Flying Fish, and Butterfly.  Then there were three new geometric models.  I displayed versions of these at OUSA NYC in June, but wasn’t satisfied with them so I folded newer improved versions.

First is my Hydrangea Cuboctahedron.  This is six hydrangea tessellations arranged on a sheet to then form a single-sheet polyhedron, a cube with sunken corners to resemble a cuboctahedron.  I changed the layout of the tessellations so that it would have a symmetrical lock formed from the four corners of the paper.  This went together easier and held better than that previous lock.  I also added another level to the hydrangea tessellations compared to my previous version.  I folded it from a 50cm square of marble wyndstone paper, which looks great and is super strong.  The model could be wet folded but that turned out not to be necessary.  I may still do it if the lock tends to open up over time.

The other two are Starball Variations I and II.  Both of these models are based on a dodecahedron, with extra creases to sink the vertices in such a way as to reveal a star pattern on the faces, again single-sheet polyhedra.  I use different geometries so that in one the start recedes inwards and in the other protrudes outward.  My first attempts were made from 35cm Tant paper, but that turned out to be at the limit of foldability.  I made two larger pentagons from a sheet of 70 x 50 cm marble wyndstone, and that enabled me to fold more accurately, and really understand the precreasing involved in the bottom half of the model where there layers stack up, so in the end they turned out much better.

I taught three classes, two on Saturday and one on Sunday.  They were my Flying Fish, Space Cat, and Beautiful Free Butterfly.  All the classes went really well, despite there being no diagrams and no document camera and projector.  I thought ahead and brought a pack of large paper with me, suitable for teaching.  Everyone finished the model, and I had time to help a few people who weren’t quite up to the requires skill level.  Hopefully they leveled up in my class.

I took a few other classes, including Beth Johnson’s Gorilla, and a Turkey and a Spider.  I’ve been thinking about an origami spider for a long time, so now I’m trying again to make my idea work.  Since it was a Chicago convention, there were a good number of folders I’d never met before, so it was great to meet them and see what they’re up to.  Spent alot of time just hanging out, folding, and going out to eat, mainly with Beth, Katie, and Jared N. from Oregon.  Also Eric, Wendy, Patty, Kathleen, June and a bunch of OUSA convention committee people.

Saturday night Jeannie and popped out right at sunset to go to the top of the Hancock Tower, which was once the tallest building in the world, and take in the view.  And it’s … flat.  There’s Lake Michigan in one direction, and the plains in the otter, and past the city they look more and more the same as the eye draws out to the horizon.

We also discovered Chicago style hot dogs.  These are great, served with pickles and tomatoes as well as the more common ketchup, relish and onions, with an extra large frank and bun.  Jeannie says Chicago style hot dogs and pizza are on the level of Buffalo chicken wings and beef on weck, and I’m inclined to agree.

Our flight home was on Sunday night.  By this time it had started to rain.  The trip home was smooth and uneventful.  We were able to watch the first half of the Bills game in a bar in the airport, and most of the second half on the plane.

All in all a great convention.  I hope they do it again.  It was a great time, and there’s still lots to do and see in Chicago.
