Adafruit Industries’ MONOCHRON is an open-source clock kit that “has an default animated display, but is easily hackable to do whatever you wish – pictured above, retro arcade style table tennis for two.” Available now, priced at $80. Product page. Video after the break.

The best part? The time changes whenever the clock “loses” — something tells us that gives one side at least a 59-to-1 advantage.
