The Planetarium :O

The ceiling clock was from the planetarium was probably one of the most intricate devices I have ever seen. At first I thought it was a little disappointing because you really couldn't see it move noticeably since its units of measurements were of days or greater. I did have a chance to go upstairs in the planetarium to see the "guts" of the clock and I was flabbergast from all the components that make up the clock. It was powered with 3 weights, one of which would only be reset at most twice a year. There was a single pendulum that timed the whole device. Watching things spin a different rates due to gear ratios was pretty entertaining to say the least.
