[gnome-love] sorry, newb question about gtk themes in jhbuild environment

[Robert Park <rbpark exolucere ca>]

Ok, so, I've got my jhbuild environment all set up, my app is ported,
everything's running well, I'm pretty happy... BUT!

Gtk3 is so ugly! It looks like Windows 95. Seriously, I want to puke.
I keep seeing all these sexy GNOME3 screenshots that look absolutely
nothing at all like the way default gtk3 looks like when I run it in
jhbuild. How do I configure which gtk3 theme is used, and what is the
name of that really nice one I always see (eg, in gnome-shell
screenshots).

I did some googling but I must not be using the right terms because I
just can't find anything relevant (it's all ancient suggestions from
2005 to use ancient programs that no longer exist).

Thanks!
