Origami ( 折り紙 origami ) (from oru meaning "folding", and kami meaning "paper") is the traditional Japanese art of paper folding.
The goal of this art is to create a representation of an object using geometric folds and crease patterns preferably without the use of gluing or cutting the paper, and using only one piece of paper.
Origami only uses a small number of different folds, but they can be combined in a variety of ways to make intricate designs.
The most well known form is probably the Japanese paper crane . In general, these designs begin with a square sheet of paper whose sides may be different colors or prints.
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.
There is much speculation as to the origin of origami.
It is generally believed that most of its modern developments occurred in Japan; however, there have also been independent paper folding traditions in China , Germany, and Spain, among other places.
Origami had already become a significant aspect of Japanese ceremony by the Heian Period of Japanese history.
Samurai warriors would exchange gifts adorned with noshi , a sort of good luck token made of folded strips of paper.
Origami butterflies were used during the celebration of Shinto weddings to represent the bride and groom.

Origami doesn't just cover still-lifes, it also covers moving objects; Origami can move in clever ways.
Action origami includes origami that flies, requires inflation to complete, or, when complete, uses the kinetic energy of a person's hands, applied at a certain region on the model, to move another flap or limb.
Some argue that strictly speaking, only the latter is really "recognized" as action origami.
Action origami, first appearing with the traditional Japanese flapping bird, is quite common.
One example is Robert Lang's instrumentalists; when the figures' heads are pulled away from their bodies, their hands will move, resembling the playing of music.
Mathematics of Origami - There are four main mathematical rules for origami crease patterns:
Crease patterns are two colorable
At any vertex the number of valley and mountain folds always differ by two in either direction.
At any vertex, the sum of all the odd angles adds up to 180 degrees, as do the even.
A sheet can never penetrate a fold
The practice and study of origami encase several subjects of mathematical interest. For instance, the problem of flat-fold ability which means whether a crease pattern can be folded into a 2-dimensional model, has been a topic of considerable mathematical study.
