...all of these models fail the most basic test for self-similarity... at best we can say that each of these displays self similarity at a single point.
A *very* simple and truly self similar model is the dragon curve from a strip of paper. A *very* complex and hard to execute model would be a Menger sponge. If I define a "measure" as being 1 at the tip of a petal of a hydrangea and 0 everywhere else, the fractal dimension of an infinite - stage model is zero everywhere ... except right at the center, but that is a finite set, so the overall fractal dimension is the same as for a point.
