Find a phase difference you like (near 10 makes a nice "phase wave" pattern) Play with other sliders to find wave pattern you like Minimal code, for clarity of mechanism
Cloned pendulums swing by sine function. They're the same length but have increasing phase (or starting position) creating a "phase wave". These undamped virtual pendulums never stop and can go through each other so we can see the pure mathematical pattern, not simulate physical pendulums Pendulums in-phase swing together (0° difference). Out-of-phase pendulums go opposite ways (180° diff) In-between (mixed) creates beautiful wave patterns
