This is my first screenshot of my theme. I think that is clean and confortable (I hope not only for ubuntu users:-).
It made by mixing some different things from various resource:
control,window: from candido
icon: from nuoveXT
background: is UbuntuSwirl
All of this came from gnome-look.org
I also use some gdesklet, the side stripers, from gdesklets.gnomedesktop.com
