To further your amazement, and amusement, you can download the actual crease pattern. Lang explains: “Conventional origami diagrams describe a figure by a folding sequence — a linear step-by-step pattern of progression. Crease patterns, by contrast, 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!…Puzzling out crease patterns can be fun; if you get hooked, there are many more scattered around the internet. Enjoy!”
It is one of hundreds of amazing feats of folding produced by Robert J. Lang Origami – each one a genuine testimony to the power of play.
Lang has been exceedingly generous in sharing his mastery of the art, and science or Origami with the virtual world. He is clearly a gifted practitioner of his art, which makes the gift of his site that much more valuable.
