Pendulum Wave

Tuned pendulums drift out of phase into travelling waves, then snap back into one line.

  • Seeded: every render is a new run, and the same seed rebuilds one exactly.
  • Vertical, square or wide, each with a course built for that shape.
  • Up to 30 seconds on the free tier, three minutes on Pro.

How it works

A row of pendulums, each a little longer than the last, starts in one line. They drift out of phase into travelling waves and patterns, then snap back into a line again.
