There is an infinity of combinations for N and D producing tons of different styles for Maurer's Rose geometries.
Moreover, for each style or geometry, any multiplicity factor may induce different aspect or effect in color "sliding".

One of my favorite style are the one obtained by a "close miss" of integer or round value (see attached figure).

But, there is so much possibilities and different style of effect or geometry that you have to explore and prospect to found your own art.
That what make it attractive to new users or students. And the corrolated explanations may have to introduce notions in trigonometry, periodicity, theory of color , and so on...

A great tool to introduce a full set of notions and practices !
