Seed Casting the disks…

Radii follow a truncated power law, scaled so the disks cover the chosen share of the box. Every disk starts with the same kinetic energy, so small ones race and large ones drift. Collisions are perfectly elastic and total energy is held constant; the hardest fifth of the hits flare like hot metal.

The sound

Volume 80%

Ring 1.00×

Collisions chime as struck metal plates tuned to D minor pentatonic: small disks ring high, large ones low, and harder hits are heard more often. Sound starts when you enable it.

Include collision sound

Sound is included by default, even when live playback is muted. The export uses the Volume and Ring settings above.

Save directly to disk · for long videos

Renders every frame and its sound from the selected seed, without the interface. Slower hardware takes longer without skipping frames. Keep this tab visible and the device awake; hiding it waits without skipping video time. One-hour 4K videos need direct disk saving and sufficient free space. Your live scene resumes afterward.
