For the few people that actually miss the old boomerang PS3 controller design—us being one of them—we have the "Tilt Sense Wireless Controller" for the PS2 (left).
It looks fairly similar to the boomerang (right), but with a slightly fatter body and slightly shorter handles. Even so, you can see where the inspiration comes from. It's only for PS2, but it is wireless and it is motion sensitive. Unfortunately there's no rumble on this either. Based on the six pretty lousy ratings on Circuit City's website, you should probably stick to the Dual Shock.
