I can see that cinema seems to be finished. Everybody has a bigger screen at home. I'm assuming eventually you won't need a screen at all - these iPhones will just project.

Who would have thought that the telephone would bring back drawing?

Anyway I feel myself a bit on the edge on the art world, but I don't mind, I'm just pursuing my work in a very excited way. And there isn't really a mainstream anymore, is there?

In the end nobody knows how it's done — how art is made. It can't be explained. Optical devices are just tools. Understanding a tool doesn't explain the magic of creation. Nothing can.

I made a photograph of a garden in Kyoto, the Zen garden, which is a rectangle. But a photograph taken from any one point will not show, well it shows a rectangle, but not with ninety degree angles.

I was 18 when I first visited London, I'm very provincial like that, but I must confess the moment I got to America I thought: This is the place. It was more open, with 24-hour cities and pubs and restaurants that didn't close.

I stay up nights and fiddle with my opera designs. It's a bit obsessive. That's why I can't do it all the time.
