Won park has been dazzling the origami community with his dollar-bill creations for some time now. He has definitely taken Orikane (the folding of bills) to a new level. At last he published his own book of original designs, collecting 10 of his better creations.

This is not a beginner's book. The diagrams assume experience, and can be a little challenging at times. The designs themselves are quite nice - especially the very complex koi, which takes practice to perfect. My favorite is the camera.

The book is packaged in an attractive box featuring a real folded butterfly model, and containing a thick stack of play-money for practice.
