If anybody's been on Google today, (and I suspect you all have :D) then you probably know today is (or was, since the day is almost over) Akira Yoshizawa's birthday. He was the pioneer of modern origami, and invented many paper folding techniques. A fascinating documentary about origami, Between the Folds explores the many genres of origami, and while it is not exclusively about Akira Yoshizawa, it does feature him.
