You know you peaked my interest when I originally read this and started doing a search, I haven't found much, just one that was real plain. But the idea I have had is to search for pictures of lighthouses then use the program that DMC offers for a free trial (save option is disabled unless you purchase it) and see how the patterns turn out, I will be trying it this afternoon after I download the program. If you are interested in the program it is at
http://www.pcstitch.com/patview/patview.html I will let you know how it turned out. I saved a few pictures the other day that looked good.
