Make A Fake Blue Moon
Apply one little plug-in to the right image and you can make for yourself a blue moon. It is so easy that you don't even have to read this tutorial, just see from the desktop capture of the moment before I clicked with the mouse.
The tutorial exists because to the best of my knowlege, this image is impossible to get with simply film and a telescope; and because I am bored and sad and very out of place.

Not GIMP related, but still an interesting apache hack.
