In 1991, I saw an interesting clock, made in the 1820's, I think, at
the Victoria & Albert Museum in London. It had a ball bearing rolling
on a rectangular metal tray. The tray had a series of channels so the
the ball's path had to cover virtually the whole surface of the tray as
it rolled. When it had made its way from one corner of the tray to the
opposite corner, a mechanism tilted the tray the other way, and the
ball was off again, back the way it came. According to the writeup in
the display, grit in the channels could throw the timing off, so it
didn't keep time as well as the inventor envisioned.
