If your the type that still wears your shirt unbuttoned to mid chest and more gold chains than Mr. T, this is the mod for you. A guy over at Makezine has used an iTunes visualizer plug in to make his own disco lights out of his computer keyboard and display. After the mod the backlit keyboard flashes in time to the music. Now you can feel like you at a rave, or stuck in the 70's anytime you want.
