MIT Student demonstrates how to solve a Rubiks Cube with relative ease.  In this demonstration the Rubik’s is a Microsoft branded cube.  And no, you can’t just peel off the stickers, that’s cheating. The video takes about 3 minutes to start really showing you anything useful.  And the personality is less than stellar, but it [...]
