All the parameters are in variables at the top. It'd be easy enough to make it an entry in the GIMP plugin. Unfortunately I don't really know the "rules" of designing a ministeck. For example, a lot of the solid color areas could easily have been filled with 2x2 squares, but were not by the programs mentioned already in this thread. Why not? Well, a grid of 2x2 squares looks boring, so that's probably enough reason.  But, then what is the rule for deciding what to do instead? For example, maybe you're supposed to use equal counts of each shape piece? I don't know, and my script merely renders the conceptually simple, boring 2x2 squares. Attached is the result on your forum icon, Lyle, except with "MapContrast" set to 0.9 (for dimmer white/black tiles).
