4Cubes is based on an idea by Tony Fisher (and a parallel invention by Sergey Abramenkov). It uses a simplified version of the YouCube mechanism. The puzzle looks like four Rubik's Cubes on a ring. The slices of each of the four cubes turn, but it is also possible to swap around little cubies between the four big cubes.
