On the iPhone I tended to draw with my thumb. Whereas the moment I got to the iPad, I found myself using every finger.

You can't believe any picture nowadays, if it's digital. You can't really believe. If you see me shaking hands with Mr. [Barack] Obama, it doesn't mean I ever met him, does it?

I can often tell when drawings are done from photographs, because you can tell what they miss out, what the camera misses out: usually weight and volume - there's a flatness to them.

We don't all see the same way at all. Even if I'm sitting looking at you, there is always the memory of you as well. And a memory is now. So someone who's never met you before is seeing a different person. That's bound to be the case. We all see something different. I assume most people don't look very hard at anything.

In my old age, I'll be in L.A.

I'm really only interested in technology that is about pictures. I'm interested in anything that makes a picture.

I have always believed that art should be a deep pleasure...ther e is always, everywhere, an enormous amount of suffering. But I believe my duty as an artist is to overcome and alleviate the sterility of despair...New ways of seeing mean new ways of feeling... I do believe that painting can change the world.
