So, I always liked this theme by pandroid (original link: DropTheme [MM]), so I ported it over to CM6. This should work on the stable build and the nightlies.
I know of one issue with my port of it, and that is that it seems like the top ongoing notification in the list tends to get a funky gradient over it. It doesn't necessarily look bad, I'm just saying I'm aware of it.
There is no font included — it's silly to pick one when every person has a different preference and it's pretty easy to do it with the packages made by Benny879. You can get either the DarkEdge font or the Comfortaa fonts in this thread. [THEME] REVOution for CM6 RC3
The Launcher shown in the screenshots is a custom dock background'd LauncherPro, which you can find at the same link as the fonts.
