Here is a smart reversi board that lets you play against a friend or AI anywhere. The Fidelity Reversi Sensory Challenger (model RSC) is smart enough to sense your pieces. It has 18 levels of difficulty and a bunch of buttons on the side for changing level, sound settings, and verifying position.
This board is pretty rare but once in a while, it shows up on eBay. You can watch the full video here.
