function setup() {
createCanvas(600, 600);
background(207, 241, 252);

ellipseMode(CENTER);
}
function module(x, y) { //creating the individual circular modules
noStroke();
fill(255);
ellipse(x, y, 150, 150);
fill(207, 241, 252); //alternating fills of white and blue to create a visual pattern

}
function draw() {
for (x = 75; x <= 725; x += 150) { // creating a grid to make a patterned wallpaper
for (y = 75; y <= 725; y += 150){

}

I really like playing with geometry and colors, so I wanted to create something that can resemble a pattern or even a visual illusion when looked at from a distance.
