Chipmunk Physics

I wanted to use Chipmunk.js in my project so I started by creating as simple a demo I could manage, based on the actual demo, and I thought I'd share in case someone would like to learn about Chipmunk through a simpler demo then the official one, so here it is:

Happy hacking.

P.S.
In case you don't know, Chipmunk.js is a JavaScript port of Chipmunk and can be found here: https://github.com/josephg/Chipmunk-js

Same demo changed to work with Enyo: http://jsfiddle.net/BFYHN/
