Steve Norris, wanting to make an unusual clock, programmed a robot to perpetually adjust a stonehenge-like arrangement of numerals. It uses a CrustCrawler Smart Arm, brained up with a Parallax Propeller chip. For some reason, I feel sorry for it and hope it has adequate vacation time.

It almost takes a minute to change from 09 to 10 that it would have to go about changing 10 to 11 luckily thats not much of a change (just spin the 0 around to a 1).
i love the little twisting flourish it does every time puts a “stone” down.
