Another of Ken Irvine's clever designs is this Rotational Cube (well not really a cube) The 3x4x4 Puzzle has a rather difficult to discover assembly. No many moves but still a good challenge I think. I spent several evenings trying to put my copy together before I was forced to break down and ask Ken for the solution so that could get back to making them! Made from a mix of Exotic and Domestic hardwoods. Woods species may differ from photo.
