GIMP Tutorials

While I don't use it often, I did enjoy using the free GIMP enough to try my hand at a cool 3D photo effect awhile back. This evening I ran across this collection of 30 cool GIMP tutorials compiled at Noupe. Sue, at About.com Graphics Software also has some GIMP goodies and tutorials. Just skimming through all of these makes me want to go do some image editing and photo manipulations.
