I was looking though the dev list there and found references to a good
introduction to image processing one of the devs there had done on
http://pippin.gimp.org/image_processing/. Recommended reading for
anyone who haven't played with such algorithms before. (And for people
who has as well.) He has apparently also made a plugin for Lua for
GIMP which allows for some flexible image manipulation
programmatically. I have to say that seems like a pretty nice thing
for making basic effects and tying them into a GUI.

Also the basic structure for how they "draw" processing diagrams is
pretty close to what I was thinking of for "work flows" of effects.
(Though theirs is better as they actually have stuff running. ;-)
