An Essay by Koert van Mensvoort, from his blog http://www.nextnature.net/ where he has a lot of interesting material on Simulacra and much else besides. He begins this essay with the following quote:
An interviewer once asked Pablo Picasso why he paints such strange pictures instead of painting things the way they are. Picasso asks the man what he means. The man then takes out a photograph from his wallet and says, “This is my wife!” Picasso looks at the photo and then says: “isn’t she rather short and flat?”.
