This pen uses a color coded tip that can be tracked by your tablet or phone's camera, making it possible to "draw" in the air. This effect can be enhanced if your mobile device is plugged into a big screen, say, via Chromecast or Airplay.

Content includes the pen, the free app and 112 clue cards -- each with five clues on each side. The idea is to guess the clue based on the sketch -- just like the traditional game. The pen is powered by one AA battery.
