I slapped a few links and logos onto the http://wikimedia.org placeholder page.
I made a temporary logo for Wikibooks out of one of the old proposed Wikipedia logos (http://meta.wikipedia.org/wiki/Logo_suggestions - number 10, by our own Magnus Manske)... I also squarified the Nupedia logo so it fit in better with the others.
