Frucht Twist

Frucht Twist is based on an idea by Melinda Green who wanted to see a twisty puzzle with no overall symmetry. Her friend Don Hatch realized there must exist such a minimal graph producing a puzzle with 3-color corners, and he quickly found the Frucht graph. He then used his computer to distribute the twelve vertices of the Frucht graph over a sphere, such that all adjacent points are at a unit distance, and all non-adjacent ones are at least a sqrt(2) times a unit. These twelve points are now the rotation centers of this twisty puzzle. The puzzle has twelve centers, eighteen edges and thirty corners. This puzzle is printed in ABS material and then vapor smoothed with acetone. It comes fully assembled and stickered.
