Rubiks Dream 360 by Henry Harrius

This just might be the "holy grail" of Rubik's Cube magic. This unbelievable shell fits over a Rubik's Cube and locks into place, so even a spectator can hold it. Then (and this is the part that is hard to believe), you can twist the cube with the shell on it. How does it work? You need to see it to believe it.
