How does 'd.rgb' work?

|while I am on the subject, I have a new derivative of blend.sh called
|intens.sh. While blend.sh combines two colors into one, intens.sh
|is designed to work with a color file, and a grayscale file, using the
|grayscale to vary the intensity of the colors. This avoids the
|'washed out' effect of you can get from blend.sh

I've heard that there is a script that will allow you to build 360
  degree aspect maps instead of 24(15degree) maps. Is this true?
  Sounds like it ought to be more than a script.
