Bram’s Cube

Bram's Cube is an idea by Bram Cohen to add eight gears to a 2x2x2 Rubik's Cube. When the top is turned by a quarter, the gears turn by one eight. For solving this puzzle, not only the 2x2x2 has to be turned to its correct position, but also the gears. This gives a classical puzzle a whole new dimension.
