Simulations

Short physics videos from Calm Collisions. Every ball follows a few simple rules, and the patterns come from those rules alone.

Press duplicator

The video's simulation, running in your browser. Pause it, change the speed and set how many new balls each press makes.

Press duplicatorA press in a ring of balls turns each ball it catches into several.

Flask mergerLittle creatures drop into a flask and merge.

Rotor crusherA spinning rotor inside a circle full of balls.
