PG: Well, thanks for those kind words. It was indeed my first genetic piece, and in fact it was just the starting point of the process. When you use evolutionary methods to make generative art you go through an iterative process. The most promising (in this case) paintings are allowed to reproduce creating new paintings as children. The best of the children are then added back into the gene pool, and the best of those are allowed to breed, and so on. The artist then becomes a kind of gardener or farmer attempting to make better and better paintings through selective breeding. To start that process, however, you need an initial gene pool. This is typically achieved by creating random genes. That’s what this piece was. It was only the first step, the creation of random genes and their corresponding paintings. One surprise, although it shouldn’t have been, was the creation of pathological genes. The system would use the genes to create scripts, and Corel Painter would execute those scripts. I was able to watch the simulated brush strokes in sequence as Painter created the paintings. In some pathological cases, a very promising painting would form, but then at the very end a giant black brush would be selected and paint over the whole thing! This is why computational aesthetic evaluation is critical to the future of generative art. If we want our systems to exhibit real or at least simulated creativity, the systems will have to exercise critical judgment. A good start would be knowing enough to not paint over the good parts! After this piece was done, I went on to iteratively breed several generations of paintings. They did indeed, in my judgment, im &
