CSS3 animation of a pendulum wave, with balls making prime numbers (under 100, bobs colour-coded by their tens in the resistor colour code, and strings by their units) of oscillations in one minute
@Jpgordon: Thanks, and for the the very interesting question. I've adapted the animation as follows. Though the frequencies are prime, I made their lengths an arithmetic progression as in reality, the 2/60 Hz pendulum is over 2000 times longer than the 97/60 Hz one.
There are indeed patterns in which some pendulums cluster, the main one being that all primes are odd except for 2.
