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,c and sliders for choosing colouring and the values of m and s. In each drawing there are 7200 circles with midpoint on a Starr curve and varying radius.
Trying out colouring: What if I use variables in the 'set pen color to'-block? This version of Starr curves has cos b t instead of sin b t in the parametric equations for the curves: x(t) = ( 2 + sin a t ) cos(t + (cos b t ) / c) y(t) = ( 2 + sin a t ) sin(t + (cos b t) / c) Thanks to Norton Starr for the idea of drawing this kind of curves.
