I began in 1976, with small abstract paintings that allowed me to do what I had never let myself do: put something down at random. And then, of course, I realized that it never can be random. It was all a way of opening a door for me. If I don't know what's coming - that is, if I have no hard-and-fast image, as I have with a photographic original - then arbitrary choice and chance play an important part.
