Pendulum wave
24 Pendulums, One Perfect Minute
24 pendulums, each a little shorter than the last. In exactly 60 seconds they drift apart, split into groups, and come back together — then the loop starts over. Colour shows which side of centre each bob is on.
The rule
Pendulums of slightly different lengths drift out of step, draw waves, and fall back into line.
