Ambiance + Adwaita = ADWANCE!
I only made the gtk3.
gtk2 and metacity included, they are Ambiance theme by Ubuntu Artwork theme.LICENSE:

ATTENTION: please download and update your theme with the latest zip which I just uploaded, it solves an annoying bug with dark background!!!
(there is still a bug with comboboxes text color, but it's a bug of gnome, it is on bugzilla...)
WARNING: this won't work (yet) with gtk 3.1, so stick with 3.0 or use another theme while i'll fix it
