Focused Monotone by Vita

Focused Monotone 2: Lines of the Cokewhore's Mirror continues trying to stay out of the way unless you click on something. They combination of grays and silver gives it a slight mirror-like appearance. I might be difficult to read for some people but the point is that you shouldn't be reading the UI anyway, unless you hover over elements or downright click them. If you want the old version you can get it in the page liked somewhere around here.
