paintmyblog.com is a site dedicated to painting on web pages. I'll write more here when I'm not dead tired.
F.A.Q.

It seemed like a perfectly sensible thing to do at the time.

Prototype Javascript Framework
Google ExplorerCanvas
Zend Framework
Only JSON is exchanged between the backend and the front ends (web site and painting app). XML is sooo pre-post-web 2.0.
