Origami Master Thomas Hull gets a flickr account, and uploads some of his old tessellation work. look and learn, people! some great stuff here. It’s like christmas in January.

:: ROGER KNOX FINE ART :: January 31st, 2006
Red Algorithm.
Sometimes you find the most interesting things via your referrer links- I found the artwork of Roger Knox, who has some very interesting abstract art!
I particularly like this one, as it reminds me of particle trails from a supercollider (physics: my first love!)
some very organic, chaotic, and unique works. Glad to stumble across your site this morning, Roger!
And of course he lives in the City by the Bay, the Jewel of the west coast- San Francisco. I need a good excuse to move there. I’m open for suggestions. anyone?

(4.6.4.12) tessellation by Thomas Hull January 31st, 2006
So on my daily early morning reading, I found this post on Tom Hull’s LiveJournal site.
He created a flickr account (tomster0) and uploaded a nice little pile of his old tessellations, as well as crease patterns for many of them.
“Oh Frabjous Joy!” was the first thought that popped into my head on reading this.
He mentions that he folded these back in his grad school days (94-95), inspired by the works of Fujimoto and Palmer.
I have to say that there is something particularly gratifying about seeing these kinds of things folded by a math professor, as his understanding of the underlying geometries is above and beyond the rest of us mathematical laymen.
Hopefully we can convince him to post these to the Origami Tessellations photo pool on flickr. They would certainly be a more than welcome entry!
This particular photo, his 4.6.4.12 tessellation, is a new pattern to me… he mentions that it’s the first time (to his knowledge) that dodecagon twists were successfully incorporated into an origami tessellation. I am also curious about his reference to the hexagonal twists as being “pursed”; I haven’t heard this term before, but it’s easy to guess what it means- and it explains, at least for me, how the hexagonal twists got that particular shape. I’ve wondered that about photos of older work by Andy Wilson, Chris Palmer, etc., but I’ve never really dug into it and tried to figure out why. So that’s a new tidbit of information for me.
Thanks, Tom, for posting these photos, and sharing your work with all of us. I’m sure that some new fruit will come from your old work, as your ideas are admired and absorbed by other folders. I’m very grateful.

Happy New Year! January 29th, 2006
From my flickr friend Tina, who is most likely the coolest teacher in San Francisco.
“Fook” (rhymes with “book”….in Cantonese) is the Chinese character for good fortune/good luck.

Star spring, standing January 26th, 2006
Mélisande folded one of Fujimoto’s designs after some long hard work looking for the crease pattern.
Here’s her flickr text:
————-
Creator : Shuzo Fujimoto
CP in book : Origami El Mundo Nuevo, by Kasahara, published 1989 by Sanrio(Japan), ISBN 4387892544.This is a baby star spring : original model starts from square paper and has 10 stars. I was intimidated by the idea of collapsing points by rows of 10, so I reduced the thing to a rectangle 12/22.
Here you see 5 stars and 2 half-stars instead of the 6 I’ve planned, I probably made a wrong valley/mountain assignement during collapse, cannot read japanese instructions.
Nevertheless, I’m glad how it turned out. It is a wonderfull model, another side of Fujimoto’s genius.
I don’t know if it should be called a tessellation ? Maybe it is closer to box-pleating ?
Infinite-origami made last year a ridged triangle tessellation that shares some similarities with the above.
I’ve seen this before, in the photos of Dribalz (Dr Eyeballs?), helpfully reminded of this by Mélisande earlier today- the link is here.
This is an ingenious design, and definitely not how I thought it would fold. As with all of his designs, I am extremely impressed.
Thanks, Mélisande, for folding this and sharing it with us.

Voronoi tessellation, test 1 (twisted) January 25th, 2006
a test piece from a new working theory of pleating.
polygons are defined by the same methodology used to make Voronoi tessellations; borders are then used as a reference crease along with the central point of the polygon to create the appropriate “fold flat” crease pattern. in this case, you can see the original 1/2 pleat creasings, which were further divided into 1/4 width pleats.
This was a test using random polygons; other methods of more usefulness (applications for use with regular polygonal shapes) are in development.
much fruit on this tree, I think. I hope I am able to refine my ideas enough to make them usable.
if you find this idea interesting at all, please drop me a line at origomi [ at ] mac.com. I’d be happy to talk to you about it.

Geometry without language January 24th, 2006
The always fascinating Future Feeder points out a story in the January 20th issue of Science, about a tribe in Brazil’s Amazon jungle which has no language for geometry but still understands it, in some cases as well as American adults. (Although as an American adult, I’m not really sure that’s actually saying much. -Eric)
There’s something a little satisfying in knowing that the human mind is capable of intuitive leaps with or without a huge societal support structure in place to coddle it.
