nouveGnome can be used with any Gnome version. But GnomishBeige on this site is for Gnome 3.8 and, because the Gnome devs don't care about backward compatibility, it probably won't wotk with v3.4.
However, you could download a version for Gnome 3.4 from launchpad.net/~webupd8team/+ar…
or launchpad.net/~noobslab/+archi…Download a version for Ubuntu Precise. If your distro isn't Debian based, extract the Debian package and use its contents.
