Krystian Wilisowski came up with the concept. It is a 2x2x2 Rubik's Cube with a twist. If you turn a face by 45°, then a new type of 180° turn becomes available. One can see this puzzle as a three-dimensional variation to Krystian's Disk.
The strange new move is available only after a 45° face turn. Then there are four possibilities for such moves. It does not change its shape even after such a move.
This puzzle reopened the debate about what a jumbling puzzle is. As of this writing there is no answer.

-The orientation of the eigth corner is determined by the other seven.
-The segments in the center of each face and the concave pieces must have the same parity.
-The corners and the convex pieces must have the same parity.
