Charming History of Portraiture

I recently bemoaned the lack of portraiture in the altfotonet.org pool on flickr. And during a discussion with one of my co-editors, came across a link to the Saatchi online site, in the top right corner is a video of the evolution of portraits, a series of well known portraits from the history of art that morp together seamlessly giving the impression of a timeless person drawn and painting from the beginning of time.
