I never stopped doing what I did as a child.

I was one of the first post-studio artists. I used to do my works in the streets. I used to find them in the streets, and I used to leave them in the streets.

If you're any good as an artist, you have to be doing something nobody else has interest in. Nobody would be interested in my work except a few crazy people.

Art is an intersection of many human needs.

I was never good at painting. The great turning point came when I had a block of wood and I carved a shape into the wood and put a small piece of timber into that space - like a negative - and so it made an endless column, only inward.

By nature, I am a materialist... It is exactly these impingements upon our sense of touch and so forth that I'm interested in.
