I put something together but haven't documented it yet. When viewing your display prefs you can select your style sheet from the drop down menu and click the view button to see the style sheet in use. Right now the display only shows a standard ubbthreads.php layout. I intend on tacking postlist.php and perhaps "my home" on also to give a good example of the styles being used.
Also, style sheets (.css) that are attached to a post have a [view] link next to the subject as well.
