var myImage;

// preloads photo of my dogs and I
function preload() {
    var myImgURL = "https://i.imgur.com/Ux0KKiz.jpg";
    myImage = loadImage(myImgURL);
}


function setup() {
    createCanvas(640, 480);
    background('black');
    // the image is too big so have to shrink it to fit canvas
    myImage.resize(640, 480);
    myImage.loadPixels();
}

function draw() {
    // chooses a random x value located near the cursor
    var randomX = floor(random(mouseX - 15, mouseX + 15));
    // chooses a random y value located near the cursor
    var randomY = floor(random(mouseY - 15, mouseY + 15));
    // selects the color from a pixel at a random point near the cursor
    fill(myImage.get(randomX, randomY));
    // draws a circle
    dot(randomX, randomY);
}

// creates dot shape
function dot(x, y) {
    push();
    noStroke();
    translate(x, y);
    ellipse(0, 2, 5, 5);
    pop();
}

For this weeks assignment, I had a lot of fun playing with the image. I used dots to create the photo of my dogs and I when I was younger. It was interesting when I was able to change the circle sizes. I stuck with size 5 because it made the design seem easy to comprehend while also not being extremely clear. I tried size 10 and it seemed too blurry.
