"Instead of a bunch of interlocking mini-cubes, it's made up of six
LED-lighted touch screens...You simulate twisting the blocks by sliding your finger along a
row of squares in the direction you want them to turn. An accelerometer
inside determines which side is facing up (i.e., which one you're
looking at), and desensitizes the other five so you don't accidentally
make a move with the hand you're holding it in."
