Houlis Cube
Click a thumbnail to see its larger version and description.
A puzzle which is based on the fourth dimensional symmetry 4D polytope known as hexadecachoron (or 16-cell).

The inventor called this "Houlis Cube" because of the X crosses which exist on each side of the cube (the Greek letter "Xi" is the first letter of the inventors name, and it is pronounced as "H" in English).

In its solved state all crosses are made of two edges of the same color. There are sixteen different cubic states only and going from one to another requires the movement of no less than three vertices. Two of those cubic states are solved states and are mirror images of each other. The goal is to go from one mirror image to the other. There are many more interesting (cubic or not) patterns than can be made with this puzzle. The movement is done by elongating and contracting the telescopic rods such that corners pass through the faces.
