A while ago I showed some screenshots of a new eye-candy theme we were working on. Then I got a little destracted and Richard was mostly busy with Clearlooks-Cairo, but recently I picked it up again and tried some different ideas. It’s still very early in development, but I already enjoy using it and I kinda like this snapshot:
As you can probably tell, it uses ideas from both Aero and Aqua. It will be anything but conservative, but still focus on polish and usability (as you should expect). The window decoration is just a quick hack of the gnome-window-decorator for compiz (which also uses Cairo), I will finish it once compiz gets real theme support.
