I just managed to install the svn Murrine with RGBA and added RGBA plugins for Rhytmbox, Epiphany, Image viewer and Gedit. Loving it! I really recommend people to give it a try if they can.

Example:



Adding the plugins was easy (just put the files in the plugin folders) but now the remaining applications I use need to be patched. Does anyone know how to 'patch' an application?
Heres a link for totem:

But it just gives a file and no real instructions.

By the way if anyone wants to know how get murrine RGBA just ask and I'll try to post the steps i followed.
