Looking for Fibonacci curve

[micheus]

By trying to fix my issue for the Marguerite center I did a study and I realize that the mini flowers arrangement is composed not only for Fibonacci sequence, but by Voronoi cells too. I used centers of three different flower density for that:

The Fibonacci spiral starts from outside to inside in which I used the same number of mini flowers - until the curve continuity finish. Then I notice that the extra mini flowers at the center look like Voronoi cells.

I think now I'll be able to produce a better Marguerite.
