Ball.js

Ball.js is a Javascript class that handles physics interactions between balls (i.e. collisions) on a flat area as well as rendering.

You can render in canvas mode as well as in html mode.

You have a bunch of display effects such as glowing, blinking, exploding (changing the radius, color, alpha) ...
