The rules are simple. The person who gets it right uploads a new one. Picture, if it is a famous painting\photo\etc it can be distorted or a familiar piece ( hand, hair, or somehow linkable to the person) or somehow distorted like an added beard or one of those fancy photomanipulationdistortion thingies. If its an older piece or less known, say like a medieval piece, then it would be nice if it was posted as full picture. Lets start with easy.
