Just in time for Halloween I guess. This USB based controller can be used for either PS3 or the PS2 and currently listed at $25. The pretty neat thing about this controller is the skull it has right in the center with LED eyes that light up, and has a facemask you can attach or detach. This could certainly scare away people you don't want touching your game system.

I think what would add some more fright to the item if it vibrated and talked at the same time, kind of like Vintage Tiger Handhelds. But I guess you wouldn't want it anymore scarier than what is already. Available at usbgeek.com
