The Tetraspinner (officially called a Cyclic Tetrahedron…) is an amazing puzzle that, when rotated creates a Kaleidoscope effect with the diamond shaped patterns coming together to form an illusion.

It can be cycled to show 4 different patterns.  Each pattern has been designed by Sue Duffy specially for the Tetraspinner.
