Here it is - eGtk for Classic Gnome Session.
Package includes: gtk theme. metacity theme and emerald theme.
To install extract .zip file, then extract .tar.gz file and folder that was in .tar.gz copy to .themes folder (hidden in your home folder).
I know that control center looks bad, but that's canonical's fault not mine (i had to choose - good looking control center or good looking beatbox, so i've choose beatbox).
Theme will be updated after 12.04 release, and after Luna release.
