PEGA's oddly-named "Vibrating Bag" adds rumble capability to your stock PS3 controller. Now they don't specify if the vibration actually works when the game generates its feedback signal, or if the thing just continuously rumbles. But couldn't your tired hands use a relaxing massage anyway?
In addition to adding some unwelcome bulk to the controller, the remote receiver that plugs into the console's USB port has a huge antenna sticking out of it, messing with your PS3's sleek good looks".
