“I draw flowers every day on my iPhone and send them to my friends, so they get fresh flowers every morning. And my flowers last. Not only can I draw them as if in a little sketchbook, I can also then send them to 15 or 20 people who then get them that morning when they wake up. Picasso would have gone mad with this. So would Van Gogh. I don’t know an artist who wouldn’t, actually.”

David Hockney 2009
