The Neurosky MindWave is a headband with EEG sensors that, paired with software, let’s you control things by thinking.

The latest gadget to use the Neurosky interface, the Puzzlebox Orbit, has a helicopter inside an orb (to keep it from damaging itself when it inevitably crashes). It comes with a transmitter that hooks up to a mobile device, software, and a Neurosky headset; the package costs $189.
