When you photograph them you cannot really tell one photograph from another. It is my understanding that with the larger works you give a certificate with a description of the arrangement of the pieces. You know, so if people feel they have to do it, no one can prevent them. Oh, it is just continuous, always the same. Actually, I work like the army in a sense, especially in war.
War is long periods of boredom and brief periods of feverish activity.
The only version of sketching I do is finding things in the street. You have been labeled in art history as one of the pioneers of minimalism. Those labels like cubist or minimalist just make it easier not to think. I was making works that became to be called minimal long before there was anything called minimal. At the time I didn't know that there were these other people working in similar ways like Dan Flavin or Donald Judd, Robert Morris and others.
