This was Oskar van Deventer`s exchange puzzle at the IPP32 Washington 2012.
There is a limited supply of this puzzle, as no more will be made.
Cold Fusion is a six-piece fusion of interlocking rings. Sliding and rotation are the fundamental ways of turning the pieces in this interlocking puzzle. The rings are notched. The object is putting the puzzle back together after turning it apart.
