Twitter is amazing. Two nights ago I watched the PBS documentary on origami, Between the Folds. Yesterday morning when I got to my office I made the following post on Twitter:

In the next 12 hours I was flooded with suggestions, comments, and links. Here are some of the book titles and links that people sent me (I’m posting them here so that I can come back and look at them when I have time). If you have any that you’d like to add, please put them in the comments below.

• The TED video, Robert Lang folds way-new origami, along with his web site and a link to his TreeMaker software (that he mentions in the video)
• Tom Hull’s web page and his book, Project Origami
• Erik Demaine’s web site
• Unit Polyhedron Origami, by Tomoko Fuse
• Unit Origami: Multidimensional Transformations, by Tomoko Fuse
• Unfolding Mathematics with Unit Origami, by Betsy Franco
• Dan McKinnon’s post on origami at his mathrecreation blog
• Kusudama: Ball Origami, by Makoto Yamaguchi
• Polyhedron Origami for Beginners, by Miyuki Kawamura

By the way, if you want to follow me on Twitter you can find me, at @divbyzero (or my newer, nonmathematical Twitter account @davericheson).

I’ll end with a clip from Between the Folds. As a research mathematician I can completely relate to the discovery that this origami artist made. However, his description of “one fold” origami does kind of remind me of a Christopher Guest mocumentary.
