To follow-up, here's a short compositing and node breakdown of my previous animation "Slumber" which you can watch here vimeo.com/16054952 or here youtube.com/watch?v=ibzsXFvEQ6w
This breakdown video was made with Blender 2.5, 2.49, and GIMP.
Audio edited with Audacity.
The .blend file of node setup will be available on my upcoming article.
Thanks for watching! ^_^
