This is REALLY COOL!

Could someone explain how this is built or give an overview of how it works? In the 'about' page http://www.chromeexperiments.com/detail/100000-stars/ it says WebGL and CSS3D, but I'm wondering how they fit together and what does what.

Is there a better way to view the source than just 'view source' in chrome?

I know a number of programming languages and I'd like to learn more about how this project works. [Saw the link to book on graphic programming in other comments below http://www.arcsynthesis.org/gltut/index.html, but how to "take apart and study" this project? ] Kudos to anyone who can point me in the right direction. Thanks!
