"Here's one that needs little explanation: one pedal activates Star Power, the other one fiddles with the whammy bar. That keeps your arms and fingers free to Guitar Hero, and since the React Standalone Pedal is wireless and works with any PS2 guitar, you shouldn't have too much hassle tossing this on to your garishly patterned carpet and proceeding to rock. It's available now for $25.  [Via Joystiq]"^^<http://www.w3.org/2001/XMLSchema#string>
