    //light beams formed by random length
    noStroke();
    fill(theColorAtLocationXY);
    //shorter beams for greater quality 
    rect(px, py, random(1), random(4, 50));
    //longer beams for greater expression 
    rect(px, py, random(1), random(50, 100));

    //placed on top layer to create a more visible image
    //end points of the beams
    push();
    rectMode(CENTER);
    rect(px, py, 3, 3);
    pop();
}

With this project, I wanted to use an image that was simple which would allow me to have an increased focus on the formulation of forms. I decided to use this self-portrait photo from the mattress factory as it only relies on black and blue. I was inspired by light beams and achieved this through randomly sized length rectangles with squares placed on the top of each randomized length rectangle. To add an additional element, I placed a rotating square that formed a circular border informed by called pixel colors.

function draw(){
    var rectX = random(width); //rectangles are placed randomly along width of canvas
    var rectY = random(height); //rectangles are placed randomly along height of canvas
    var rectSize = 10; //size of rectangle
    var ellipseSize = 10; //size of ellipse

    //constrain rectangles to canvas size
    constrainX = constrain(floor(rectX), 0, width);
    constrainY = constrain(floor(rectY), 0, height);
    
    //get and fill colors according to picture underneath
    imageColor = imageUnderneath.get(constrainX, constrainY);
    noStroke();
    fill(imageColor);

    //ellipses are drawn instead of rectangles when key 'e' is pressed
    if(key == 'e' || key == 'E'){
        ellipse(constrainX, constrainY, ellipseSize);
    } else{
        rect(constrainX, constrainY, rectSize, rectSize);
    }
}

This project was very interesting, however, I didn’t know how to approach it at first. I wanted to have some sort of interactive element to my self-portrait project. In my final piece, I chose to switch the shapes that the code draws in, from rectangles to ellipses.

function draw() {
    //random pixel 
    var px = floor(random(width)); 
    var py = floor(random(height)); 

    //color variables for that pixel 
    var cx = constrain(px, 0, width - 1); 
    var cy = constrain(py, 0, height - 1); 

    var colorLoc = portrait.get(cx, cy); 

    noStroke(); 
    fill(colorLoc); 

    //person (rectangles)
    if(px > 120 & px < 430 && py > 30 && py < height){
        rect(px, py, 5, 5); 
    }
    //background (ellipses)
    else{
        ellipse(px, py, 10, 10); 
    }
    
}
  

This project was very interesting to complete. I enjoyed the process of playing with different shapes to complete the different colored sections that worked together to form the portrait. I wanted to use larger ellipses in the background to create a more hazy background.
