Origami is far more than paper cranes these days. With a thriving community that pulls the best of art and engineering together, the boundaries are getting pushed further and further in ways that are both beautiful and exciting.
The documentary is a little slow paced, but I recommend sticking with it because it really does deliver. Just seeing what can be done with a single fold is worth the price of admission.
To add to the story, there is a copyright dust-up between popular origami artist Robert Lang (seen in the documentary) and contemporary artist Sarah Morris. Morris took the folding patterns from dozens of origami creators and turned them into vibrant 2D paintings that have sold for hundreds of thousands of dollars. Lang and others are suing Morris for copyright violation.
Copyright in the artistic domain has always been a tricky issue. It will be interesting to see how the issues of derivative vs. transformative work shake out in front of a judge.
