The Whiteboard Clock is the brainchild of Zurich engineer Maurice Bos and uses a robotic hand to erase the time and rewrite it every five minutes. Pretty cool, but when I read about a clock that ERASES TIME, I expected to see something a little more impressive. Like a cross between a time machine and a black hole.
Keep going for a very short video of the clock in action.
Thanks to Gregory, who is like an extra fancy Greg.
