I think I've always been afraid of painting, really. Right from the beginning. All my paintings are about painting without a painter. Like a kind of mechanical form of painting. Like finding some imaginary computer painter, or a robot who paints.

Here's one from me: 'You have to be aware that everyone else is thinking far too hard about themselves to be thinking about you, whoever you are.' If you want it, you can have it. Once you know that, you can be free.

I just wanted to find out where the boundaries were. So far I've found there aren't any. I just wanted to be stopped, and no one will stop me.

Art comes from everywhere. It's your response to your surroundings.

Even as a kid in drawing class, I had real ambition. I wanted to be the best in the class, but there was always some other feller who was better; so I thought, It cant be about being the best, it has to be about the drawing itself, what you do with it. Thats kind of stuck with me.

I did a butterfly show in Berlin, and we had a guy who's an expert on butterflies; who bred them all and who looks after them all in the space.

Art is the closest you can get to immortality, though it's a poor substitute - you're working for people not yet born - and people want it because it is brilliant. It ends up in museums anyway; the rich have to give it back to the people, it's their only option. There are no pockets in a shroud.
