Pendulum Waves and Hidden Symmetries

David Peeples sent me a view of the video (above) today - thanks, David - featuring a ball pendulum, which takes on interesting patterns when viewed from the side. Technical aspects of this "wave" effect can be found on this Harvard page.

Interestingly, the symmetries we see above are not the same ones we see below - the same variety of experiment now viewed from the front (and above) of a similar pendulum.
