A simple, lightweight physics engine written in CoffeeScript
...Because it is lightweight, it integrates easily with 2D renderers like Canvas or WebGL, and it is popular in generative art sketches and interactive experiments.

It’s ideal when you want expressive motion and playful dynamics rather than full rigid-body simulation.
