Brushes are a convenient way to add many standard image components to an image. You take the PaintBrush tool (
) set the brush, and click where you want an image. Brushes can be geometric patterns or "real" objects. Some brushes, called "Image Hoses" (.GIH extension, in Gimp) can output a different image each time (for instance various shapes of tree leaves).
From what I have seen, most sigs use a background.
I don't know what a fractal is (besides a mathematical object).
Sig creators are a bit of a cult, with their own rituals and aesthetic canons. I have yet to understand what they call the "flow". It's obviously very important but no-one can define it...
