The intersections between origami, mathematics, and science occur at many levels and include many fields of the latter. Origami, like music, also permits both composition and performance as expressions of the art. Over the past 50 years, I have developed nearly 800 original origami compositions. About a quarter of these have been published with folding instructions, which, in origami, serve the same purpose that a musical score does: it provides a guide to the performer (in origami, the folder) while allowing the performer to express his or her own personality through interpretation and variation.

One uncut square of Korean hanji paper, 12", 2004, a composition in the series of crustaceans.
One uncut, untrimmed sheet of handmade paper, 12", 2003, a composition in my series of origami mammals. Classical origami is "one sheet, no cuts." But we still have to cut the paper to square. Or do we? This figure is designed to use an untrimmed sheet of handmade paper; the rough, irregular deckle edge is used to realize the mane.
One uncut square of St.-Armand paper, 8", 2007, a composition in the series of mammals.
One uncut 1' x 4 rectangle of Wyndstone 'Marble' paper, 6", 1998, a composition in my series of human figures.
One uncut square, 15", 2002, a composition in the series of origami fish.
One uncut square of Wyndstone 'Marble' paper, 8", 2003, a composition in my series of origami mammals.
One uncut square of Canson Mi-Teintes, 6", 2013. The work, designed at the DRUPA trade show, is a composition in my series of origami mammals.

One uncut square of custom-made Origamido paper, 12", 2010. I designed this composition to show off the beauty of Origamido paper, which, I felt, matched the subject perfectly. This figure is folded from a sheet from a special batch of handmade paper, which was custom-designed and pulled at the Origamido Studio with the guidance and assistance of master papermakers Michael LaFosse and Richard Alexander.

Crease patterns (CPs) provide a one-step connection from the unfolded square to the folded form, compressing hundreds of creases, and sometimes hours of folding, into a single diagram! A CP can sometimes be more illuminating than a detailed folding sequence, conveying not just "how to fold," but also how the figure was originally designed. Mathematical and geometric CPs usually show all the creases, but representational origami rarely shows every crease in the finished form, as it would make the crease pattern impossibly busy. Instead, the crease pattern gives the creases needed to fold the "base," that is, a geometric shape that has the right number and arrangements of flaps. It is still left up to the folder to add thinning and shaping folds. - Robert J. Lang
