A custom designed working ball clock built entirely using LEGO parts.

For those that have noticed, no it does not keep accurate time in the video. I just wanted to show off the mechanical components of the clock. In the video it is running off of a standard LEGO 9V motor, which ends up picking up a ball every 55 seconds. In order to keep accurate time, an actual timing motor/controller has to be used. This could be easily done using the LEGO mindstorms system.
