Style XP. It allows you to customize a lot of stuff. If i recall correctly, you can set a random desktop and theme. It also allows you to change the bootscreen and login screen. I would suggest that you don't use the bootscreen feature. I had a couple of crashes follow soon after I changed the bootscreen. Just use it for desktop and themes and you'll be fine. here's the link to the program demo...i'm pretty sure you know how to "fix" it.
