I was listening to an IT Conversations podcast on Computational Origami by Robert Lang and the designs sounded interesting so I checked out his website, Robert J. Lang Origami and was amazed at the complexity and richness of designs that can be obtained using a single, uncut sheet of paper.
Keep in mind that many of these designs take hours to fold not to mention to come up with the design in the first place. But, in making use of computers to help calculate how to work the paper, he shows here designs that were once thought impossible. Especially the insects.
If you have a moment, check this out. It’s truly amazing.
