Yes, Mattel. From the people who brought you Hot Wheels, you will soon be able to purchase an EEG and accompanying game set.

The sensors measure theta-wave activity in your brain; the waves are directly related to your level of focus and concentration. The sensors register the theta-wave activity, translate that activity into a signal, and transmit it as a radio frequency to the Mind Flex.
The more theta-wave activity there is, the faster the little fan in the unit will spin. The speed the fan spins at, and therefore moves the ball, is based on how hard you concentrate. The faster the fan spins, the higher the ball goes along the Z axis. Turn a dial and move the ball along the X and Y axis.
