Looking for a four column theme..

I have a comic that I post from and I’m using a content management system different from comicpress. Getting the comic up there has already been solved, but now I’m having to take apart the theme I’m using to make the sidebars and whatnot get out of the way of the comic.
So here’s what I need: I’m looking for a theme with one long column going across the entire page, and three smaller columns all underneath it. Anybody know of a theme that fits the bill?

here’s the link btw of my (definitely unfinished) blog in question: http://tomcatltd.com/wordpress/
