check out the post your desktop thread, many people have it and will let you know where they got the skin.
right click on desktop, click properties, change the theme.

EDIT: Or do you mean themes that don't come with XP?
You can change the XP theme to green or silver by right clicking on the desktop then going to properties-> appearance but otherwise you can change the skin.
There are only 7 official themes for XP. If you want different one you need to hack your system which slows it down.

Blue, Olive and Silver ship with XP, the other 4 you have to download.
