Hands Free 3D - Control Your Avatar WITHOUT a Mouse of Keyboard

This is just too cool!

The possibilities here are vast. I can see a mashup between Guitar Hero and Second Life, for example, where you are on (a virtual) stage, jamming with others, or running a marathon, or even playing Quiddich!

While build initially for virtual worlds, this has many applications to gaming. Imagine a WoW raid where you finish dripping with sweat from swinging your sword several hundred times! Fun and exercise at the same time.

If you are building a house, plan for a BIG family room. In the next decade, we'll be duking it out with our family members, moving about, getting in shape, and having fun. Oh, don't forget the extra wiring when you build the room!
