This is really cool. Someday, when I have a man cave/game room, I want to put this clock in it.

It’s actually an open source kit available from Adafruit Industries. The computer is truly playing a game of pong, and the score changes every 60 seconds to track time. Not sure I’d want to bother with soldering it and all that, but I think it’d be worth buying a finished one. Adafruit has a short video showing how it works, the link is below.
