HalloGTK is a dark orange theme created because there was a lack of dark orange themes for GTK.
It is one half of the full theme HalloGNOME, which I am working on a metacity theme for as well (not pictured). I will post a full theme, as well as the metacity theme, when it is finished.
Also, there is a panel pic in the theme that is not configured to be the default pic yet. To use it, right click on each panel you have, click properties, click background, click the backgroud image radial button, click browse, and go to ~/.themes/HalloGNOME/gtk/ to double click on the image. Have fun with this theme!
