Origami (???, origami^?) (derived from "ori" meaning "to fold", and "kami", meaning paper) is the ancient Japanese art of paper folding. The goal of this art is to create a given result using geometric folds and crease patterns. "Origami" refers to all types of paper folding, even those of non-Asian origin.

Origami only uses a small number of different folds, but they can be combined in a variety of ways to make intricate designs. In general, these designs begin with a square sheet of paper whose sides may be different colors. Contrary to most popular belief, traditional Japanese origami, which has been practiced since the Edo era (1603-1867), has often been less strict about these conventions, sometimes cutting the paper during the creation of the design.
