Anyone knows what is the system that allow blogs / websites to generate a random picture for anonymous commenters? Its always the same picture if you input the same name and email, seems very useful but can't track down what it is.

It's used here on stackoverflow, and I've seen it on a number of other sites and blogs.

Thanks!

Cool! Does Gravatar handle the lazy registration too? As in, it created me a profile here on stackoverflow? Thanks a lot!

Identicon is what I was really looking for, but the Gravatar answer allowed me to find it! Thanks Jeff! I assume the lazy registration is handled separately then.
