Brain waves->Game Movements

I'm talking about this brain sensor technology from a San Jose company called NeuroSky. The company has created algorithms that measure brain waves or electroencephalograms (EEG) and turn it into simple game movements.

I played a modification of Half Life using a sensor on my head. I then used a mouse to click on objects in the game, like a chair, ball or desk. When I had the right level of attention, I could summon the object to me. It's like telekinesis. If I click a different button, identify the same object and then relax, I can get the thing to levitate in place.
