“Mindball is an experience product, a game where two players control a ball with their brain waves.”
“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. “
Here we see two calm Mindball competitors focusing on fierce relaxation so as to ensure victory over their more excitable opponent.
