Fold the paper so that it reach the given shape.
David Mitchell's (England) website contains a lot of paper folding-related puzzles.
History of the puzzleEdit
Although Origami as a toy existed in Japan for at least 600 years, its application to geometry was first described by T. Sundra Rao (India) in 1893. Huzita–Hatori axioms are an axiomatised form of paper folding, described in 1991. The problem that asks whether a given fold pattern can be folded into a flat surface is shown to be NP-complete in 1996.
