National parks, zoos, protected areas, polluted seas - using the whole world as a readymade, I thought about it as a stage set. To activate a stage set you need a drama, an actor to offset it.

Really the moment I decided I wanted to do art seriously, I left art school. I wanted to be with people who were interested in the same things I was: popular culture.

I'm so extremely well prepared for negative response, I've taken precautions.

Of course, I'd welcome protest. Good criticism is hard to find.

The Stonehenge proposal got a lot of interesting criticism. One of the best - or worst - said something like, "Go home to Las Vegas." I think this project could possibly be realized at a very late part of my career. Right now, I don't have the authority, the budget, the credibility.

My purpose isn't to be confrontational. My purpose is to find out about the world and play myself against it to the extent that it is even conceivable.

In a way I am saying the nation-state doesn't exist, borders don't exist, you can try going anywhere. It is a kind of pre-Internet consensus I always had in me.
