The Defualt Avatar

Or, as I have been calling it, Annonyman. 

They have always been of interest to me. Every web company with a community has had to solve the same problem of designing one, and here at GroupMe, I’ve been working on our version of the ever ubiquitous graphic.

While researching, I put together this image of as many as I could find.
The Vimeo avatar is a favorite of mine, as well as CollegeHumor and Flickr.
*Bonus points for being able to spot them above. 

Here is a great post by Dan Meth, talking about how the Tumblr Avatar may be the most veiwed drawing he has ever done.

Love these. I think I have to go with the Vimeo one being a favorite as well. Though the Unabomber one is pretty great.
