ItÂ’s a pretty amazing piece of engineering, containing a high-speed infrared camera, accelerometer, plus it has Bluetooth communication, a vibration motor, speaker, buttons - and it does this all running off two AA batteries for a long time.

If you had talked about this a few months before it was released, I probably would have said it could not have been done, given my exposure to research. But they did it, and I was massively impressed.
