It is very cool. I wonder how long it will be before they develop the technology so you can think "up" or "down" or "left" or "right" instead of make a fist with your right hand. I mean, if I was in need of the technology, I'm sure I would adapt. I just wonder if they have to do it that way because the signals for those movements are more superficial than what it would take for up/down/left right.
