There is an ancient Japanese legend that says, if you fold 1,000 paper cranes you will be granted a wish
The world's smallest paper crane was made with a 0.1 by 0.1 mm sheet. The largest measures over 78 m.
Origami is derived from two Japanese words that mean folded paper.
As part of the 50th anniversary of the dropping of the atom bomb on Hiroshima, 250,000 paper cranes were created and displayed in each city. Each crane contained a name and the message, "A paper crane is the symbol for world peace".
Origami originated from China.
Some Origami models even have moving elements.
Origami has a strong link to mathematics, and has been used to create practical solutions for many problems (such as airbags). This has caused alot of copyright issues due to design theft.
