Fifteen uncoupled simple pendulums of monotonically increasing lengths

[Fire Walk With Me]

dance together to produce visual traveling waves, standing waves, beating, and (seemingly) random motion.

The period of one complete cycle of the dance is 60 seconds. The length of the longest pendulum has been adjusted so that it executes 51 oscillations in this 60 second period. The length of each successive shorter pendulum is carefully adjusted so that it executes one additional oscillation in this period. Thus, the 15th pendulum (shortest) undergoes 65 oscillations.

2. That is simply too cool! I believe I must build one of those to

put on the coffee table in front of the couch. Had the original maker of the "executive pendulum" thing thought of this, there would be one everywhere.

Marvelous, and thanks!

7. Looks like #2 and #10 are slightly off

but that's nitpicking.
