Darkness-RGBA with a bunch of mods
Patched gnome-panel to do rgba properly (though unfortunately the code is really hacky and a lot of the stuff is left improperly or unimplemented since its unnecessary for this situation)
Patched dockbarx.py to draw a little saner on rgba
Patched murrine to adjust the transparency as well as to remove special-casing of panel drawing.
This, along with compiz, emerald (which I need to go over and fix someday damnit...I wrote/patched half that code and its a mess! -- yeah I'm Quinn Storm, go by other names other places, heh), a reflection.png I put together for the reflection plugin, a wallpaper I put together out of a photoshoot I found on flickr I really liked, and of course blur and such.
I just wish firefox could play nice, but its not using gtk really...and there's no other browser option that I know of that does adblock plus.
