@Borat Sister,
												It's amazing what we can see in these tiny avatars.  I look at 
Craven's avatar and see one those snow monkeys:

It's a regular A2K Rorschach test with every post!
When in doubt, go to the profile page.  A larger version of the avatar is usually there (except, strangely enough, for 
Borat Sister -- what can explain that?).
The solution, of course, is to make the avatars bigger, and thus more legible.  So far, that has been my one-man crusade.
