Here's a game at CES coming out that measures your concentration (brain beta waves, or something) and turns on a fan to levitate a ball. That's seriously awesome.

Just the beginning of consumer mind-to-machine technology.

Here's a USA today article about the force trainer - basically, you reach 'Jedi levels' by levitating a ball in a plastic cylinder higher (thus requiring greater concentration).
