This is one of Gila O’s folds, which is a very nice example of one of Alex Bateman’s crease patterns. I just keep mentioning that guy today, probably because we had a few email exchanges- his work is kind of stuck in my head!
Gila’s nifty stuff is at http://www.flickr.com/photos/87477835@N00/, she has some newly created folds there as well. check out some of her new work and let her know how cool it is!
