Pit and the Pendulum

Griffith Observatory's Foucault Pendulum. It was made to prove that the planet rotated. What it does is just swings back and forth, and as the Earth spins, it moves one of those pegs near the bottom in the pendulum's path, which knocks it over. It hits a pin every 10 minutes. I wanted to capture the motion. The pendulum itself consists of a giant sphere with a needle on the bottom.

 

I wanted to capture some motion to it, so, there you go.
