Google了一下，叫做Identicon -> http://en.wikipedia.org/wiki/Identicon

“An Identicon is a visual representation of a hash value, usually of an IP address, that serves to identify a user of a computer system as a form of avatar while protecting the users' privacy. The original Identicon was a 9-block graphic, and the representation has been extended to other graphic forms by third parties.”

有些挺漂亮的，有些略戳。
