Second Life Brain Control?

I have heard of second life before this class, but after talking about it my curiosity got to me and I looked around on some of my favorite gadget blogs. This comes from a gizmodo article last year and I thought it may be of some interest to the group. This looks like a basic brain control device made by a university in Japan. It allows the use to just think of walking and translates it to keyboard strokes to move a second life avatar.
