I found an interactive page for generating wordpress themes at http://www.yvoschaap.com/wpthemegen/. It’s a very nice bit of Javascripting that lets you use your own logo image, control body size, sidebar location and size, choose a 2 sidebar or 1 sidebar layout, control the menu layout, and control all the colors. The result is a very lightweight wordpress theme with a minimum of images, though you certainly could further modify the CSS to add your own background graphics, etc..
Compared to my own interactive CSS manipulation scripts, this is an impressive bit of programming. The script not only generates the css styles, but also zips up a WordPress-complaint theme package that you can just drop into your wp-content folder. The theme is also Widget-aware and supports tags.
