You might have the vaguest of memories seeing this piece before -- it made a cameo in an Engadget Show segment -- but here we are with a much clearer picture of Adafruit Industries' Monochron clock, now also on sale! As is its modus operandi, the timepiece is open source... but should you plan on sticking to default, you'll be gifted with a great retro-style Table Tennis for two. The best part? The time changes whenever the clock "loses" -- something tells us that gives one side at least a 59-to-1 advantage. See for yourself after the break.
