Rolling ball clock (WIP)

This is a project a very long time coming. When I was around the age of 10-11, I was invited into the basement of a family friend, and there sat a stange contraption aptly labeled "Time Machine". It was nothing more then a clock, one that uses steel balls as a display, but nonetheless, 11 year old me's curiosity was piqued.

It has since been a goal to design and build my own. Ive made a couple of attempts, but until recently, I never had the design/building skills or maturity neceasry to take on such a project.
