I also want to see these shapes, but I understand the reasons they are more difficult to achieve than the shapes with simple certex figures. The best I can think of is an analogue of the Trajber’s octahedron which has the same cutting planes as a normal 3x3, but in its dual shape. i.e. its a vertex-turning octahedron instead of a face turning cube. I’m not sure how vertex-turning puzzles would work in MC4D, since the current interface works by clicking the face which has to turn. However, with the number of puzzles currently available, I’m not that bothered about seeing any of these realised.

In reply to your PS, several octahedra exist, such as the Trajber’s I mentioned, and the recently mass-produced face turning octahedron.

I was playing with the puzzle inventor, and I was dissapointed that they were not appearing when I typed their symbols in. Is it because there is no obvious way to slice such shapes into puzzles, or is it just that the program does not support four cells per edge for some reason? It seems like these puzzles would be fairly new experiences, as I can’t really think of any simple analog of either. Sounds fun.
