I have black background for headers and grey background for normal text (plus a sort of lavender color which I find quite pleasing). Just switched over from lithium and couldn't be happier.

I LOVE the graphic element up top–the raised fist within the Vitruvian "A" is inspired but I find the white text on the black background a tad hard on the eyes. Some folks with vision issues might have a tough time. Could another theme, say, I don't know, Oxygen, be modified to incorporate the Erik's logo?
