Star Wars Science Force Trainer

Interesting! I was big on this stuff seven years ago, when I found a "Star Wars Force Training" toy [1] -- you put the brain wave sensor on, which passes a signal that sets the strength of a fan that's blowing upward on a ball in a tube, and therefore its height. So it makes a neat brain-ball-height link. Unfortunately, it was really unreliable -- only for brief periods could I (or anyone) consistently set the height.
I also bought the OCZ Neural Impulse Actuator that you could use as a PC peripheral and it could detect alpha/beta brains waves as well as tension and eye movement, but which I really only found reliable for the last two. (You control tension by "gritting your teeth".)
