    //after a certain number of frames

    else if (frameCount > 1000) dev = 240;

    //randomly assigns position
    var px = randomGaussian(width / 2, dev);
    var py = randomGaussian(height / 2, dev);

    //contrains random values to the canvas
    var picX = constrain(floor(px), 0, width);
    var picY = constrain(floor(py), 0, height);

    //retrieves color from pixel at random coordinate
    var col = pic.get(picX, picY);


    strokeWeight(2);
    stroke(col);
    noFill();

    //retrieves a random index for the letter array
    var i = floor(random(25));

    //draws and rotates letter

    translate(px, py);
    rotate(radians(angle));

This project was a lot of fun, and I think really helped me understand more about coding with images! I spent a lot of time experimenting with different ways to project the image – vertical lines, spirals, etc. I decided on letters because I thought it would be cool to have a variety of complex shapes to compose a single image. This is an image of my friend Dani that I took last year.
