At CES last week, NVidia showed a demo of its new GeForce 3D Vision on a 40-plus-inch screen playing Guitar Hero. (For more details on the product, click here). I threw a pair of the glasses over over camera to give you an idea of what rock'in in 3D is like. Clearly, you won't get the full effect--but you'll be able to see some difference. In person, it was pretty amazing.
