Description: An Expedit that changes colours according to your moods? Why not? Michu added some LED modules controlled by an Arduino behind the bookcase and now, it practically dances with 10 color sets (RGB, Rasta, CGA, Brazil, Fizz, Kitty, Neon, Lantern, Lemming, LeBron) and 6 animation modes (random, solid, ordered, checkboard, weird, weirdtwo).
Best thing yet, you can change the color set or animation mode with a flick of your toes on the PS2 keyboard attached under the bookcase. The keyboard has a special key map installed, if a key on the left side is pressed the color set change, if a key on the right side is pressed the animation will change.
