But fixed background images can be REALLY distracting unless they're very simple. Although the same goes for tiled backgrounds if they're not seamless and/or too flashy. If it's really detailed (hint hint) , it's usually better (and less distracting) to have that detailed background at the top of the page and slowly fading to the wiki's background color (like this).
