Made a custom user profile theme the other day, it's really feminine so I don't recommend using it if you're a manly man. You can see a preview of it and get all of the theme information (colors/images) here. To get the information, simply hit the "Customize My Profile" button on that page. To get everything working functionally, you may have to use your brain a little bit. For example, if you just put the image as "page background", by default it will repeat on x and y. When you disable that, it will have a white background by default, so to get everything working appropriately you need to set the background to black, save it, and THEN swap it out for the image. Feel free to give me any requests.
PS. It also occurred to me that if you're really savvy at this sort of thing, you may be able to simply take that pages HTML and edit in your security token, then just hit customize user profile and hit "save".
