 In 1939, Arthur Stone created the HEXAFLEXAGON. Stone really did come from England, his new American paper was too wide for his old English binder, so he cut the edge off. Fiddling with strips of paper, he made the hexaflexagon. 

A hexaflexagon is made up of equilateral triangles, and only equilateral triangles will work. Depending on how many triangles you use, equilateral triangles create a series of endless combinations.
