I remember the first time i ever started gimp. It was on this OSS CD i bought (because back then, you bought your OSS software on CD because downloading was to expensive and would take to much time).
It was even worse then MS Paint, it had this Motif GUI and looked horrible, it also couldn't do much, i didn't leave it installed on my system.
Second time i tried it, there was no need anymore to buy a CD and it was included in the distro. Motif was replace by the Gimp ToolKit and Gimp itself was able to do already some nifty stuff.
