Tessellation of Hydrangeas Originally uploaded by Tangomath. Some really nice work recently from Jorge Lucero, of Brasilia, Brazil. Jorge was one of the exhibitors at the Tessellation exposition there last month, and his work was huge- and very impressive! Since then he’s made some new work, including this multi-hydrangea tessellation. Very good stuff, and very precise- it was a joy to look at his folding there, as it’s absolutely accurate. (Although that is perhaps what one would expect from a mathematician…) Thanks for sharing this, Jorge! website: http://www.mat.unb.br/~lucero/orig_e.html (english) http://www.mat.unb.br/~lucero/orig.html (Portuguese) his flickr page

Need a Photo for the Blog Originally uploaded by oschene. Philip Chapman-Bell (aka Oschene on Flickr) has been doing a lot of fascinating exploration of twists lately, including some spectacular 16 sided chrysanthemum shapes and this particularly delicious 10 pointed twist star. True to form, after sorting all this information out he went further and published a full sequenced crease pattern (SCP) for this design, and released it under the CC License. I am a big fan of his SCP work- it’s clear to see and understand, and is a lot more thorough than a basic CP while being easier to create than a full diagram set. And I have to give him a big hand for releasing his work under a CC license so others can freely use, share, remix, and reuse his designs. Thanks for sharing this with us, Philip! Here’s some more of his stellar work:

Lightbox Testing: Joel Cooper, RAW vs. JPG (Origami Tessellations) Originally uploaded by EricGjerde. Hey there- I’m doing some testing with a lightbox setup, and I could use some feedback. I’ve got a few photos in my photostream- more to come tomorrow- and I would like to know how they look at full resolution to you. good? bad? fuzzy? clear? I’m leaning towards shooting RAW files and doing a lot of post-processing, but it’s a lot of work to do. Maybe I’ll need to switch to film or actually go out on a limb and find someone with a 12+ Mpixel digital camera to do this thing right. Anyway, take a look- http://www.flickr.com/photos/origomi or look on my Photos Page and click on “Recent Photos” to see them. Thanks for your feedback. -Eric

triplet 2 Originally uploaded by origami joel. My friend Joel Cooper created this wonderful mask, with three interconnected faces. He brought the prototype for this piece with him to NYC and to our Brazil tessellation expo, but to see the finished work (and so quickly!) is really a pleasure indeed. It seems like something from mythology- take your pick: Greek, Roman, Norse, Chinese, Egyptian… almost all mythological stories involve a multi-faced figure in one way or another. And, admittedly, the work is a little creepy- the realism he achieves only serves to further this, I think. Many of Joel’s masks approach the Uncanny Valley in terms of their similarity to actual human faces. I don’t mean to lend credibility to this pseudoscientific theory, but for some of his work I find them strangely appealing and at the same time rather scary- perhaps because they do indeed seem like human faces frozen in time (and paper). For this reason, I think, my favorite mask is still the one that hangs on my living room wall: mostly …
