Good to see origami on the front page.

For those who are interested in the field - whether as art, for the fun of folding or the various potential practical applications - the best book on the subject by far is Robert Lang’s Origami Design Secrets[1], which is a fantastic read and covers all of these and more. Lang is a mathematician at heart but also a consummate artist. I certainly can’t recommend origami enough as a hobby.
