From Slashdot, introducing Mindball:

Mindball is an experience product, a game where two players control a ball with their brain waves. The player being most relaxed wins the game. The brain waves are detected by sensors attached to the headbands. The sensors (electrodes) are connected to a biosensor system. The biosensor system, registers the electrical activity in the brain – so called EGG. The brain waves increasing the chance to win Mindball are called Alpha- and Theta waves. They occur when we are calm and relaxed. The player´s brain activity is shown in a diagram on the monitor. The player being most relaxed makes the ball roll over to the opponent´s goal, with his brain waves as only aid, and thereby wins the game.

What I find fascinating -- and ironic -- is that, not counting medical items, the first commercial item on the market that responds to brainwaves actually rewards you for thinking less than your opponent. Isn't this a dream product for a corporation? Buy our product and put yourself into a state of hypnosis. Now you are under our power. The Utopian-novel-like implications of such an item are frightening to me. And considering the 2000 election went to the opponent with less brain power, the Republicans can't refuse the public access to such a game.

On second thought*, the Republicans in the pockets of the corporations may outlaw it nonetheless. After all, it's the first sport where the performance-enhancing drug of choice is marijuana.

*See? I already lost the game.
