This Rubik’s Cube from ThinkGeek isn’t going to make those of us who can’t solve them feel bad about ourselves. Instead of a
torture device puzzle, this Cube is a 5W external speaker. There’s no internal battery; it’s powered by USB. It can connect to any audio device using the included 3.5mm audio cable. The Rubik’s Cube Speaker is 3.5″ cubed, naturally. It’s $29.99 at ThinkGeek.
