Well, what do you have so far? Post your code!

If you have no code, try starting with an empty sketch! Can you do a blue background?

your starting point:

float x,y,i; void setup(){size(400,400);} void draw(){ while(i <= 20){ i+=PI/10; x=sin(i)*i*PI+200; y=cos(i)*i*PI+200; ellipse(x,y,i,i); } }

For an interactive sample, try the following code. Set the mouse close to the top left corner to get your sketch.

Kf

float x, y, i;
float ko=200;  //Repetition frequency
float ks=200;  //Amplitude

void setup() {
  size(400, 400);
  fill(255);
}


void draw() {
  background(92);
  ko=map(mouseX, 0, width, 5, 400);
  ks=map(mouseY, 0, height, 0.5, 10);
  i=0;
  while (i <= 20) {
    i+=PI/ko;
    x=ks*sin(i)*i*PI+width/2;
    y=ks*cos(i)*i*PI+width/2;
    ellipse(x, y, i, i);
  }
}
