Puzzles and origami, mainly Modular origami, have many similarities. Since both are my hobbies, whenever I bring a modular model to the puzzle lovers meetings, they all try to disassemble them and see the mechanism, how the units are put together. Here is a classic Russian puzzle, translated into paper, by Francesco Mancini, from Italy. Mancini loves this combination of origami and puzzles and his flickr site is full of them. This version of a cube is very similar to the traditional business card cube, and assembly is just as simple.
