The following code only seems to draw to the screen every time the central fill colur (fillColour) changes in the for loop in draw(), and yet in draw() I call myDrawing() on every loop of the for().  I also note that when fillColour2 is printed to the console it comes twice, like this is being called twice, when I only expect it to be called once per iteration of the for().  Could someone more experienced than I with Processing point out the error of my ways?  I want to draw all 4 ellipses every cycle, changing the fill and  stroke colours for each ellipse, with the exception of the  inner ellipse which I want to change the fill colour for only every "centreCycles" around.  Thanks  in advance, Garth



float x;
 int centreY;
 int centreX;
 float fillColour = 0;
 int centreCycles = 50;


void setup() {
 size(1200, 800);
 x = width/4.5;
 centreY = height/2;
 centreX = width/2;
 background(0);
 //frameRate(12);
 
}



void draw() {
 smooth();
 strokeWeight(8);
   
 for (int i = 0; i < centreCycles; i++) {
   if (i < (centreCycles - 1)) {
       myDrawing();
       //println("fillColour: " + fillColour);
       
 } else {
     myDrawing();
     fillColour = (random(255));
     println("fillColour2: " + fillColour);}
 }
}


void myDrawing() {
   for (int i = 4; i > 0; i--) {
     stroke(204, random(255), 0);
     fill(204, random(255), 0);
     ellipse(centreX, centreY, x*i, x*(i-1));}
 
     stroke(random(255), 102, 0);
     fill(fillColour);
     ellipse(centreX, centreY, x, x);  }
