Of course, the '60s was a study in decadence. Everything just got worse and worse, and at the end of the '60s, everything was so horrible that people were killing each other.

Actually, New York is great for playing around. I made a lot of studies for New York-a big vacuum cleaner lying on the Battery in Manhattan.

I had no idea what art was. There was one art class in high school, but it didn't make a big impression on me. Then I went to college and thought I'd become a writer.

I knew I wasn't that good a writer, and all I could remember was that I could draw. I'm better at drawing than I am at writing.

I am for the art of underwear and the art of taxicabs. I am for the art of ice cream cones dropped on concrete.

I knew I had to take my ambition more seriously, so I enrolled at the Art Institute of Chicago. Then, in the fall, I went on a tour of my own. I didn't go to New York because that was too well known for its art scene.

The right angle is one of the world's basic shapes.
