Hi Daniel,
I've built this skin (http://www.wiki-babel.org/en/Main_Page) based on

I can't claim it's a work of art and
I've been making some improvements to the skin system for awhile now, so...
If you have a MediaWiki skin you've built, feel free to bring out it's
source code. Currently most of the few custom skins that exist are
floating around the Internet, and they are various degrees of out of
