Pendulum Wave
Fifteen pendulums of slightly different lengths released together, drifting in and out of phase to draw travelling waves, snakes and chaos before snapping back into line every cycle, with glowing bobs and thin wires.
How to use it
Run the real thing here, tune it, then copy the prompt that rebuilds it.
- 01Launch and look
The preview is the real three.js scene in a sandboxed frame, not a recording. Everything responds to you.
- 02Dial it in
Swatches recolour, sliders move the parameters that matter, Randomize finds what you would not have typed. Structural changes rebuild the geometry.
- 03Pick your stack
Single HTML by default, or a Next.js, React, Vue or Astro component that imports three from npm.
- 04Copy the prompt
It carries geometry, motion, camera and material intent with your values, in build order.
- 05Iterate one element at a time
Geometry, then motion, then camera, then material. Scroll and hover behaviour usually takes a second pass; that is normal.
