Steve Norris's house must be full of robotic marvels. He's got that RoboStool we showed you, and also this creative clock that uses a robotic arm and a series of 14 numbered cards. He's coupled a CrustCrawler Smart Arm with a Parallax Propeller chip, and surrounded the arm with a semicircle of cards — it'll arrange them appropriately out in front of it, displaying the correct time. It may seem slower than an ordinary clock with three hands, but there's a definite charm in watching Norris's Stonehenge Clock move about.
