I am a relative newbie to WordPress, plugins, and shortcodes, but not to html and css. Here are the sites I have worked on so far using the Ultimatum Theme Builder and a lot of intense shortcodes:

http://collegestudentpressurewashing.com (pressure washing)
http://atlantarocks.com (indoor rock climbing gym)
http://valentinafair.com (advisory: adult content)

I am in the process of working on two more WordPress sites, when they are ready to view, I will add them here as well.

If you have any comments or suggestions on any of these sites, please let me know.
