SelflessPortraits is the brainchild of Jeff Greenspan, chief creative officer at Buzzfeed, and freelance artist and advertising creative Ivan Cash. The idea is that people have their Facebook profile pictures transformed into portraits by strangers picked at random. So far, over 13,000 drawings have been submitted from over 91 countries. The site has had over 100,000 unique visitors and is averaging about 400 submissions a day. (There's also the opportunity to become Facebook pals with your portrait painter.) A gallery of portraits and the original profile pictures can be seen here.
