A recent update finally brought dark toolbars for Ambiance, but that's not the only interesting recent change in Ubuntu 11.10 Oneiric Ocelot. There's also a new window switcher (which currently uses CTRL + TAB instead of ALT + TAB by default, but this is probably temporarily - at least according to the tooltip in CompizConfig Settings Manager) as well as new Compiz Grid plugin animations.
Here are a few screenshots:
