Thank you Robert!
From the articles, it appears the inspiration was a model form the desk of C R
Calladine who, after a little more research, seems to be pretty big in
tensegrity structures. I can see how the triangulated cylinder pattern (also
Kresling pattern is succinct) - could have arisen from investigating this kind
of structure. Thanks again for the tip.
Its nice to have a narrative for the development and discoveries.
best, Matthew
[Origami] World Origami Days 2017
Hey, it's October 24th - that's the start of "World Origami Days" ( https://origamiusa.org/wod, http://www.origami.gr.jp/WOD/2017/ [in Japanese]) WOD is a multi-week celebration of origami spanning from today, October 24th, the birthday of Lillian Oppenheimer (founder of the first origami group in the US) to November 11th, which is Origami Day in Japan. The goal is to share the joy of origami, world wide, in any way you can. I encourage everyone to fold something (at least one thing! you have two and a half weeks!) and post it online somewhere, and send us a link here on the list. (Remember, you cannot send images *to the list itself*.) If you like, you can download an official "World Origami Days 2017" label and put it in your picture, get yours here: http://www.origamihouse.jp/wod2017/Application.html There's a Flickr group, too: https://www.flickr.com/groups/worldorigamidays/ And of course posting and sharing other's photos on Facebook is a fine way to share the fun (and let your non-origami friends about this cool thing you do.) To start it off, I folded the "Makoto Rose" by Yamaguchi Makoto; here's the blog entry: https://gofoldsomething.wordpress.com/2017/10/24/yamaguchis-makoto-rose-wod-2017-1/ Enjoy! Anne
[Origami] Happy origami days
Wow it seems it went unnoticed this year! Someone just reminded me, so happy origami days for everybody and go fold something and spread the word. -- Jorge Jaramillo
Re: [Origami] Stone paper for origami?
Boesner sells "Steinpapier" (stone paper) that claims to be made from 80% limestone powder, not using any wood. It is basically impossible to rip and very heavy. I know a couple Origami friends (f.e. Melina Hermsen, Daniel Chang) who work with it, but personally I didn't see the value. For me it feels and behaves very weird. Nice Greetings Anna
