From Mashable:

The Puzzlebox Orbit, which launched on Kickstarter last November and debuted Tuesday at the 2013 International CES conference in Las Vegas, is making waves with its brain-controlled helicopter toy. We saw it in person, and were tickled by the ease with which you could pilot the device.

From NeuroSky — the same company behind the quirky brain-controlled Necomimi Cat Ears — the helicopter can actually move up and down via brainwaves.

Here's how it works: By wearing a Bluetooth headpiece with sensors, the Puzzlebox Orbit converts brainwave data into flight commands. The helicopter shoots into the air when you concentrate hard, and can be lowered when you relax the mind. Infrared signals are transferred to an accompanying iOS or Android app to measure your level of concentration. Users can set up focus-goals on the app ahead of time, and the controls work once your concentration reaches those sweet spots.

The Puzzlebox Orbit also runs on an open-source platform, so developers can hack and personalize their experience.

Price: $189.
