Sony has just filled a patent for what appears to be a racing handle with a PS Move slotted in the center. At least that's what it looks like.
The patent even comes with visual instructions on how it's supposed to work, although you're supposed to use it standing. It looks like something you'd see on a jetski or a bike, but we can hardly fathom what games Sony intends to use it for.
Needless to say, we'll only find out what it does come E3, when Sony announces a new game that ends up using the odd-looking device.
