}

function draw() {
    var x = floor(random(img.width)); //random x location for ellipse
    var y = floor(random(img.height)); //random y location for ellipse
    var imageColor = img.get(x, y); //picking the x, y coordinates from the image
    fill(imageColor); //fill the ellipses with the color from image
    //let the points get smaller toward the bottom of canvas that has more details
    var pointSize = map(y, 0, height, largePoint, smallPoint);
    ellipse(x, y, pointSize, pointSize);
}

This project was entertaining as I was able to recreate my own portrait by using points. Observing how the points would gradually generate the full photo, I purposely made the bottom half points tiny to better reflect the detailed areas.
