Lego Undamped Wave Pendulum V2

Thirteen uncoupled pendulums of monotonically increasing lengths, swing together by electronic oscillators to display patterns that look like traveling wave, standing wave, and beat mode. The period of one complete cycle is 60 seconds. The longest pendulum was adjusted to complete 52 oscillations in this period. The length of each successive pendulum was adjusted to complete one additional oscillation during this period.
