Like regular sized Guitar Hero and Rock Band guitar controllers, but far, far daintier, the USB ready Riff Rocker adds hand [[link]] cramping as an extra difficulty modifier to your rhythm gaming.

While the lil’ device has been available commercially for a few months now, it has been so at some of the more, let’s say, unproven retailers. But we got a chance to go claw-hand on with it at CES this weekend. It works, but only with the open source Frets On Fire for Windows and Linux.

And it really only works as a fun little novelty, the kind of thing that someone might while away their time with between CES appointments. It’s certainly [[link]] more accurate than I had expected — my Pixies “Wave of Mutilation” score was respectable, if not perfect — but limited in its usefulness.

At $19.95 though, this is either an expensive prank or a very frugal, very space conservative option.
