Thanks for listing this in the GIMP Script catalog. I've done about a dozen or so different scripts for GIMP. I will put a lot of effort into being lazy! I use GIMP because it's free, and I don't have a copy of Photoshop.

Some of the scripts I've done are really silly ones (making a Yin-Yang diagram...which I did mainly to muck around with selections) while others may be of use here (Planet, Gas Giant, Planetary Rings) I have one that I'm working on now that will do a star. When I get that one set, I'll post it for comments if so desired. Or should I just go ahead and post them all so everyone can comment and laugh at them?
