rotate(n * 0.3);
for (int i = 0; i < n; i++) {
float a = i * radians(137.5);
float r = c * sqrt(i);
float x = r * cos(a);
float y = r * sin(a);
float hu = i+start;
hu = i/3.0 % 360;
fill(hu, 255, 255);

I don't know about your code, but I can help. Did you make a button in HTML? If you didn't plan to do that, then why not run the functions?
