termGTK is a dead simple gtk theme.
It aims to stay out of the way and tries to resemble a cli environment, so that you won't notice so much you're using a gtk app.
I made it for myself and I didn't test it too much as I'm not using many gtk apps at the moment, but it seems to work fine.
The original source was terminus http://gnome-look.org/content/show.php/terminus?content=108928.
It fits quite nicely with my 2px openbox theme http://rent0n86.deviantart.com/art/2px-169820163

Please comment if you like it or if you have any suggestion, and feel free to fav'it!
