The puzzle's name describes the intention for this puzzle. It is a rhombic dodecahedron which faces are split up through spherical cuts which have so far been typical for the Rex Cube. Just like the Rex cube this puzzle is vertex- (or corner-) turning.
So far everything sounds as if it were just another shape transformation. The main point for this puzzle is that turns are possible for every axis going through a pair of opposing vertices. This puzzle is therefore a hybrid which collects the two axis systems of a face turning hexahedron (known from a 3x3x3) and the corner turning hexahedron (known from Rex cube and others).
Since the rhombic dodecahedron has the same symmetry group as the 3x3x3 and the rex cube this puzzle does not change shape. It does not allow jumbling turns.

One year after this creation the designer presented the Rex Rhombic Triacontahedron. The same principles are applied to a Rhombic Triacontahedron.
