Mattel MindFlex (2009)

Wouldn't it be great if we could control all our technology without touching it at all? We're not there yet, but the Mindflex offers an early glimpse of mind control's capabilities. The toy comes with a headset that uses the player's brainwaves to help move a ball through an obstacle course. The mind itself isn't actually moving the ball -- instead, a fan built into the device is triggered by the player's brainwaves. Concentration makes the fan blow stronger, lifting the ball higher, while a relaxed mind does the opposite.
