We saw this Wii PC peripheral knock-off while strolling through the halls of CES this weekend.
The fact that the oddly-named CyWee Z lets you play the likes of Shaun White Snowboarding with motion on your PC wasn't all that interesting. What was interesting was that the controller transformed from a straight Wii remote like stick into a gun shape.
I can't imagine they will sell a single one of these.
