Pollock is supposedly the initiator of the "Abstract Expressionism" movement in art with his famous canvases with paint dripped and poured upon them.

I think, however, that Mother Nature perfected abstract images before him, as exemplified by this random picture through a hedge backlit against the blue sky.

As for being "art" or "artistic" I believe there are better examples of skill and imagery presented in contributors' PADs than on the walls of any museum of modern art...........
