If your a fan of our site, your already familiar with the invisible clock - it consists of just needles but no clock face. Well, now we've got the inverse - a clock with a face but no needles!!!
The principle is as innovative and simple to explain. There is a magnet that slowly moves around the clock's backside while a metal ball on the clock face moves along with it. The magnets together and tell time perfectly!
Note that with this single ball the time displayed is approximate - within 10 minutes. If you need more precision than that - chill out, your too stressed!
