For example, this is a demo site for the new alter-egos.
Its only a demo and not fully functional, but I imagine we can have a play.
Its very very clever. You design yourself, choose one of the demo characters and then if you select email, you will get sent 8 images of your own charicature !
Now if I was a media agency I would want this. I imagine I would be able to sell it to brand marketing managers and say "look at what happens to people when they assocaite with your brands." The viral message could then be sent from email to email. The receivers of the characters could then go a build their own.
