Hey all,
I am dabbling with creating some 'computer screen' maps. Think those nice bright green maps used in Sci-Fi or similar styles.

Has someone created a tutorial to do that sort of thing? At the moment I'm looking to basically update these quickly-thrown together jobs I've done as part of a game project.

All help or pointers are greatly appreciated. I'm going to be working with GIMP mostly, since Inkscape is still a very foreign entity to me.
