I recommend that you look at swirl.c in xscreensaver: http://www.jwz.org/xscreensaver/ It makes nice swirly patterns based on the distance/angle of each pixel from a random set of points. Shouldn't be to hard to add lines/shapes to the algorithm as there are plenty of good closest-point-on-shape algorithms out there. An editor for this sort of gradient, attached to GIMP gradients and all other GIMP goodness, would be great fun.
