If you go to the theme subforum for the Tour, you can view a number of the themes yourself. Many folks post image shots of the main screen and some of all screens.
I have found an older L-theme I like by hubbard (forget first initials)
I second the "Classique Docked" I was using the free "Classique Lite" but purchased the premium as soon as it was released. I have a couple others installed but really like the Classique!

+4 for Classique. Premium comes with hidden icon (hidden today or non-today). And even come with space bar access for QuickLaunch. Simple beauty like this is in, home screen covered with icons are out, in my opinion.
This one I use all the time. Looks great, works well, and doesnt zap your battery. I like some of the transition ones, and one called bliss but they seem to eat up my battery and memory for some reason.
