Using the CSS Text Wrapper, you can wrap text on a web page to fit any shape that you can draw. You use the drawing tool (seems to be flash-based) on their site to create the shape to which you want the text to conform. When you are done, you can then get results which are in-line CSS, CSS using classes, or javascript.

If you've ever tried to create interesting, arbitrary, shapes to define your text on a web page, you know how hard this can be. Using this site, it'll take you all of one minute to get these results. And the service is free.
