No, the GIMP isn't a lame person, a twist of silk, or a weird little guy locked in the basement (see Pulp Fiction for that last...). Or at least in my case it isn't. The GIMP is an image manipulation program (a general one) that is similar to Adobe's Photoshop. It is a fairly powerful program, and it makes creating cool graphics a snap. You can find out more about the GIMP at it's homepage.
Below are some GIMP tutorials I've written, mainly for helping myself remember how to do things. If you have any problems, or have a better way of achieving the same effect, please email me!
