var originalImage;

function preload() {
    var myImageURL = "https://i.imgur.com/g3iK76T.jpg";
    originalImage = loadImage(myImageURL);
}
function setup() {
    createCanvas(480, 480);
    background(0);
    originalImage.loadPixels();
    frameRate(500);
}

function draw() {
    //defining the variables
    var px = random(width);
    var py = random(height);
    var ix = constrain(floor(px), 0, width-1);
    var iy = constrain(floor(py), 0, height-1);
    var theColorAtLocationXY = originalImage.get(ix, iy);

    //drawing the random dashes
    strokeWeight(4);
    stroke(theColorAtLocationXY);
    line(px + random(-10, 10), py + random(-10, 10), px + random(-10, 10), py + random(-10, 10));

    //drawing the random ellipses
    fill(theColorAtLocationXY);
    ellipse(px, py, random(1, 8), random(1, 8));
}

I chose to make a portrait of my friend Chelsea. It was fun to experiment with the random sizes and positions of my ellipses and lines.
