[gentoo-user] Installing themes, and all the cool things I see on gnome-look.org etc

[Yoav Luft]

Hi,
I guess it's not exactly a gentoo question, but I don't figure out how to
setup all does themes/applets/eye-candies I see in gnome-look.org and
similar sites. I can't find a decent documentation and I'm sure I'm missing
something which is right under my nose.
So, where should I look?
