Living off the Grid

My reason for investigating patterns in my own paintings by doing black and white drawings of them is to actually question the whole idea of ANY artwork being "spontaneous". If there are patterns in the work of an artist, such as those found by using fractal geometry on the pieces, then isn't the artist aware of that, at least on some level of conciousness? Maybe the eventual matching of the appearance of the work-in-progress with the (hidden) mental image in the artist's mind is what causes a work to be judged "finished" by the artist.
