For this puzzle the concept of the Circle cubes was applied to a 2x2x2. The images do not show it but this puzzle has only two logical layers per axes. On one side the sectors do not move when the layer is twisted. This is shown in the second layer. While performing this move the opposite sectors do not move with the corner pieces.
This puzzle is equivalent to the void fused cube. The corner pieces are equivalent to the fused cubes corners. Two opposing sectors together are equivalent to an edge of the fused cube. The six center pieces are missing. Three pairs of sectors do not move relative to one corner, the blue-white-red-corner in this case.
Edge length: 65 mm
Weight: 237 grams
