Saw this at the Bakken...

Saw this at the Bakken museum, and laughed because it was super relevant to my project. It's a game in which you win by relaxing the most... the headgear monitors your brain waves. There's a decrease in alpha waves (another kind of neural oscillation) as you relax. The headgear detects this change and that results in the ball moving towards your opponent. The game is called 'Mindball'
