I remember reading an article on this!
It said it works better with kids rather than adults....but I would have trouble using this because I sometimes have troubles controlling my thoughts O_O
But this is truly amazing, but I think this is just the beginning of this kind of stuff...people ten years from now are going to improve so much on it...and then its actually going to be fun!!!
I cant imagine anybody actually using this on a game..but it will probably just be fun the first couple of times.....after that it probably wont be as impressive
