Color Cubes is a keyboard controlled game that basically duplicates the (in?)famous Rubiks Cube puzzle. This game came out when the physical cube's craze was still running high. I personally found it a little to awkward to use, compared to the real cube. One nice feature, though, was that it allowed you to save your cube in progress, so that you could continue where you left off at a later date.
