Similar to Namco’s neGcon for the original PlayStation, the DualShock Vortex features an “unusual design in that the left and right halves of the controller [are] connected by a swivel joint and thus the halves can be twisted relative to each other.” Click here for first picture in gallery.

You twist the controller, the dude on the screen twists the throttle, things like that. But it seems like it would have pretty limited uses, and would probably get on my nerves quickly.
