Origami!!

Origami (Japanese: ori, to fold, and kami, paper lit. "folding paper") is the 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-Japanese 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, and usually proceed without cutting the paper. 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 or starting with a rectangular, circular, triangular or other non-square sheets of paper.

History:
Although some historians argue that Origami originated in China, it is generally accepted that its actual development as an art form occurred in Japan. Origami was mostly a traditional art for the amusement of children until Akira Yoshizawa spurred a renaissance of the art form with his new advancements, including wet-folding and the Yoshizawa-Randlett system of diagramming. In the 1960s the art of origami began to spread out, first with modular origami and then with various movements developing, including the kirikomi, purist and pureland schools of thought.
