APNG
APNG stands for Animated PNG, an extension to the PNG specification to allow for animated PNG images. Similar to how Animated GIF is an extension of GIF. Create such a thing.

Project Details
The project is broken up into several stages:
1. (complete) Create an extension to the PNG Specification. Stuart Parmenter and Vladimir Vukićević did this in around 2004.
2. (complete) Implement the APNG spec into libpng. This was done for libpng 1.2.10 during the summer of 2006. Patch available on the APNG implementation page.
3. (current, fall 2006) Implement the modified libpng into Mozilla.
4. Attempt to get the APNG patch integrated into libpng.
5. Fail.
6. Give up.
7. Try again.
