I thought it would be nice to have a thread dedicated to GTK Themes, and sharing what ones we like. It's not quite the Show Your Solus thread in that this isn't about the full setup, widgets, Conkey, etc; just themes.
Sadly, I can't start this off properly since I'm looking for one I like myself; something with nice grays and less "black all the things!". So, what themes do you guys happen to like?
