Ancient Chinese Puzzle - The Tangram
This Hook and Loop Tangram set really does encompass the spirit of the diverse cap they were cut for - you will need to buy a ‘Hook and Loop 59Fifty’ though first for your patches to stick to!

The puzzle is very old and is basically a square cut into 7 geometric shapes, which can then be transformed into hundreds of possibilities!
Have Fun.
