I would like to continue being radical. As you get older, some of the world catches up and it's passed you. In the '60s you were on the crest of a wave because you were part of the wave. I don't want be a stick in the mud and do the same thing as I did last year, I want to do something different and see what happens.
Steel is such a nice material to use. It can move. It's terribly easy, you just stick it or you cut it off, and bang! you're there: it's so direct. I think Manet was very direct, he didn't prepare his canvases like Courbet, he just put paint straight on and it's very like that with steel.
