I did a lot of trial and error until I kindof got a result that matches the elementary feeling - a little.
I don't know of a way to get rid of the menubars (hide them,'globalmenu' them or 'menubutton' them).
Icon theme is just the elementary mono dark icons from the elementary-icon-theme package of the elementary ppa - I always delete the trash folder icon, tho. Personally I prefer the Humanity one.
The tar.gz contains:
* Almost-Elementary gtk2, gtk3 and metacity theme. (metacity is basically just adwaita in a little less... HUGE) (goes into /usr/share/themes/ )
* gnome-shell-theme - the theme folder for gnome shell - directly taken from /usr/share/gnome-shell/ since I don't use extensions.
You should know what you are doing if you want to use this. And make backups.
Man I can't wait to see what DanRabbit is cooking up for gtk3 - thats going to be pro.
