Computer-Generated "Art"efacts
This reminded me of a local art installation which has a six-foot-long, eight-inch-tall, scrolling L.E.D. display. The display is hooked to a computer which uses Markov chains in its programming to produce an endless stream of English-language, free-verse "poetry". I wouldn't call the device's output poetry, but it can be very amusing and entertaining.
The human's use of the image-generating software mentioned in the article seems more like a human looking at the typewritten pages of many monkeys, picking one that looks usable, and editing it a bit. The final product may be visually interesting/pleasing, but based on the relatively-low amount of human input into the image-creation part of the process, I wouldn't call it "art".
