From the README

A live demo can be found here. A demo for testing ObjectGrid performance can be seen here.

The demo uses a uniform grid for space partitioning in order to do a faster neighbour lookup (basically collision detection) with a lot of objects.

We basically just draw a line between two particles if they are within a certain distance from each other.

Particles also have a simple spring acceleration towards one another, which can make for some complex looking shapes.

The grid algorithm and basic idea is presented in AdvancED ActionScript Animation by Keith Peters.
