I claim no artistic ability whatsoever, but I do admire it. The track this thread is taking reminds me of a story I heard about Jackson Pollock, known as Jack the Dripper for the painting gimmick that made him famous.
In his youth he and his father would sometimes go behind a barn in snowy Cody Wyoming and pee curves in the snow. Supposedly this early "training" inspired his later paint swirls. The story sounds apocryphal, but I heard it from a person who heard it at a Pollock symposium.
So Haggis, you may be onto something big time here. Too bad you shared it with us. Artistic types are always "borrowing" ideas. Good luck, but don't quit your day job.
