## Description
This is a simple JS script that uses [three.js](http://threejs.org) to render
star particles in a isothermal sphere potential (this makes a nice flat rotation
curve). The star particles have their motion followed using a simple
Leapfrog/Velocity Verlet integrator. You can interact with the galaxy by moving
your cursor accross the field, and a perturbing mass will follow your mouse
around.
