'Rolling Ball Clock' is typically over-simplistic. Invented by William Congreve, it relies on the constant of gravity to provide timing divisions... the problem is, it takes no account of frictional forces, so is basically one to be consigned to the 'quirky' brigade. Contrary to popular (and stupid) belief, this is NOT a perpetual motion timepiece - it relies on gravity for 'timing' but a spring for stored energy. Accuracy depends on the cleanliness of ball and track, so basically unreliable!

I always wondered if it was possible to create movement without the use of electricity or human powered power for eternity.
