Rubik's Cube!

Ah, the Rubik's Cube. The bastard of a toy that makes most of us bleed from the eyes trying to figure out. Like Tetris, it can be highly addictive. But unlike Tetris, this cube can be hurled across the room and cause damage to things and people. Not good. It's been haunting people ever since the 80s.
And people who can actually do this make my eyes bulge. I need the secret.
