I don't know of any particular poster child for the proper wiki look, but the Eye Candy page looks pretty good.
It would be nice if it had a few more screenshots. And really, I don't think it says much about Beryl, which is a step above anything else on that page, really. It mentions Compiz a lot, but there isn't even a link off that page to get you to a Beryl setup.
Surely someone can add some Beryl pics there? And perhaps some links to Beryl pages in the wiki?
