This guy has a lot of dust (being from Texas), a couple of cars, and some paintbrushes. The results are solid if not jaw-dropping, until you realize they're in dust, on the back of cars...http://www.dirtycarart.com/gallery/index.htm
As a writer, I place a lot of value on permanent record of my creations--stories not just written down but preserved for all time in the pages of some publication or another, like publication is some thing worth more than the story itself.
But there's something neat about transitory art like the dust art this guy creates--chalk drawings, or etch-a-sketch art, or a storyteller telling a story aloud to a group of friends. It has a value to it that makes me look at what I do a little differently. Yes, this guy gets some Internet Fame (and maybe some contract work) out of what he's doing, but I think he'd probably be doing it anyway, just for the love of it. Something to think about when I'm slaving over the hot electrons trying to get a story to come out right.
