This tool was born from the daily toil of finding sample avatars for UI mockups, and created by Caleb Ogden. If you have suggestions, mention them to @calebogden. If you'd like to complain, I'd be happy to listen, otherwise you can check the faq section for more information.

Update, October 2016
Hi friends, I recieved a note from Amazon this week "EC2 has detected degradation of the underlying hardware hosting your Amazon EC2 instance [uifaces]. Due to this degradation, your instance could already be unreachable." I've set up this temporary version of UIFaces while I rebuild!
