Scene
Pendulum wave
Pendulums released together, each with a period slightly shorter than its neighbor's. The column turns into a wave, a checkerboard and apparent chaos, then realigns at the end of the cycle, in a perfect loop.

Parameters
The same controls as the editor, with the same range. The default is what the example page uses.
| Parameter | Range | Default |
|---|---|---|
| Pendulums | 3 – 15 | 9 |
| Amplitude | 0.2 – 1 | 0.7 |
| Cycle | 10 – 60s | 30 |
How it usually ends
Measured by the engine with the default configuration over a fixed sample of seeds. No number here is an estimate.
This scene has no natural ending: it runs for the chosen duration and loops. Here, timing out is the expected behavior.

- The fraction of the video where event density peaks. Close to 100% means the best moment is at the end.
Seeds that end well
No seed in the sample reached the search threshold. These are still the best ones.

Frequently asked questions
How do I make a Pendulum wave video?
Open the scene in the editor, adjust the parameters, try a few seeds and export to MP4. Rendering happens in your browser and costs nothing.
Why does the same seed always give the same video?
The simulation is deterministic: fixed-step physics and seeded random numbers. The same seed with the same parameters reproduces the same video on any machine.
How long is a Pendulum wave video?
The video ends when the scene ends. The median duration measured in the sample is in the outcomes section, and the seed search shows each candidate's duration before rendering.
Can I use the video on TikTok, YouTube and Instagram?
Yes. The export is a vertical video with audio, ready for Shorts, Reels and TikTok. On the free plan it carries a discreet watermark.
How do I pick a seed that ends well?
Use the editor's seed search: it simulates dozens of variations without drawing and ranks the ones with a late climax. The seeds on this page came from the same heuristic.
Make your own variation
Open the scene in the editor with one of the seeds above, or let the search find another.
