There are 200 metronomes. 1 loop around will take 1 hour. This is a 1 hour long pendulum wave. It has 200 metronomes playing around and will turn around for every orbit.
Beware, there are bugs in the project with the metronomes turning, if you see a metronome not in the right place, it drifted away because the screen lagged. Make sure to click the green flag again if this happens to you!
