Thinking of the negative space generated by the space-filling algorithm rather than the individual shapes might help see the fractality. This link uses a similar algorithm and discusses measuring fractality of the output http://paulbourke.net/texture_colour/randomtile/ http://paulbourke.net/texture_colour/randomtile/
