Theming for notification-daemon?

Given the standard Sonar theme in Gnome on openSUSE and the shift towards darker colours (which I pushed a bit darker, but still grey rather than black), I wondered if anyone knew of any alternate themes for notification-daemon that fit a bit better? It seems kind of neglected compared to other things and only has the one theme.

Aaron Bockover made some changes back in 2007, but they seem to have been lost. Fedora made a Nodoka theme, but I think that was mainly making it yellow and rounding it a bit. Someone else started one that’s like Ubuntu’s new NotifyOSD, but that doesn’t seem to have been finished and the last I can find it was a bit unstable.

Surely there’s either an alternative or some other themeing somewhere. Or has it never been interesting/easy enough to work on?
