Turbo mode (shift+green flag) unless you want to see the process. The values of three variables a, b and c are randomly chosen integers (see inside for details) so there are many different drawings. Press v to show/hide the values of a,b and c. In each drawing there are 7200 circles with midpoint on a Starr curve and varying radius.
Just a work in progress . . . but in the early morning, my brain still half asleep, I found it oddly pleasing to look at ;-) Parametric equations for the curves: x(t) = ( 2 + sin a t ) cos(t + (sin b t ) / c) y(t) = ( 2 + sin a t ) sin(t + (sin b t) / c) Thanks to Norton Starr for the idea of drawing this kind of curves.
