Although you should note there are two images, a white fractal set and a black one. I could add additional images, make the background larger so it doesn't need to tile as much and a bit more, but I don't really have much in the way of larger fractal patterns to use, so it'd seem repetitive anyways.
Of course I've been trying to work out the Supporter Username visibility problem for a while but I can't seem to find a proper color that'd stay within the parameters of the color scheme I'm trying to stay with.
Now i could create a less dense sort of background for the primary/secondary content areas, that might actually make text easier to read, but at the same time, I don't want to use a solid background color...because you simply can't do transparency without using an image.
