This is the NewHuman theme from the Ubuntu Intrepid Ibex alpha adjusted slightly to use the Rezlooks engine. It's a rather esoteric theme, but if you're into flat tones instead of glossy effects, or dark GTK2 themes instead of pastels, it might appeal to you.
As it goes it's not much of a theme since it's really just the original theme from the human-theme package, with lines commented out that would offend the rezlooks engine. After that, there's no changes to the original theme.
Credit goes to the people at the top of the gtkrc file; I take no credit for any real work with this.
P.S.: It probably goes without saying, but I feel obligated to mention that this theme won't work very well without the rezlooks engine installed.
