"Madcap" might be a good description, in the sense that, say, a psychotic with a Whoopie Cushion is "madcap."

If the world were fair Jessi Buchanan would wield supreme power and the global currency would be designed around an image of a guy with a paralyzing fear of forks. The world being what it is, we can just be grateful that artist/provocateur Buchanan is painting again. Even better: He's got a weblog. Which means you can now pull back the curtain and peer into his crazy pinwheel of a mind. Do it now. It's like if the Blue Man Group were one guy, and not blue, and a painter, and actually funny.
