In Process p5 Sketch

I want to add more animated elements to this. I have a couple ideas but I would like some input on what I could do. One of my ideas is animating the circles maybe by making them move or having them go from smaller to bigger. I added an image of a page out of my favorite book because my name is the main character which I think is really cool. 

let img;

function preload(){

img = loadImage("assets/book.jpg");

}

function setup() {

  createCanvas(1280, 720);

  noStroke()

  stroke(12)

}

function draw() {

    image(img,0,0);

  background(0,50);

  for(let y= 0; y <= height; y += 40)

    {

      for(let x=0; x<=width; x += 40)

       {

        fill(0,99,218);

        stroke(255);

        ellipse(x,y,10,10);

        }

}

   /*

    stroke(255,0,0);

  line(mouseX,0,mouseX,height);//gray line

    stroke(0,255,0);

  let mx=mouseX/2+60;

  line(mx,0,mx,height);//black line

  */

}
