Hey, I published a fun Cat avatar Generator. Enter your name, and get a cat!
You can play with it here:
It's the same code that builds the avatars on the blog now,
[update] Git source code is available
if you want to get more information about why I did it,
read my article My fight against CDN library,
a full chapter is about this generator.
