    fill(locationXYcolor);
    rect(pixelX, pixelY, size, size);

    //faster on right, slower on left
    //smaller pixels on right need to run faster to show imge
    if (mouseX > width/2){
        frameRate(10);

For this project, I used my brother’s photo, which I took for his high school senior d. I was playing around with pixel sizes and frame rates. The smaller mouse x is, the smaller the pixels are. Because smaller pixels take more time to draw out a bigger part of the image, I made the frame rate faster for them.I gave the pixels light blue outlines to give the image more of a “mosaic” feeling.

    var stroTwo = random(1, 10);

    noStroke();
    fill(theColorAtLocationXY); //fills with the color at that particular pizel
    stroke(theColorAtLocationXY);
    strokeWeight(stro); //randomized stroke weight so stars are unique
    drawStar(px, py); //draws star at random x and y position each time draw is called
    line(px, py, px+rando, py+rando); //pritns "tails" connected to stars

    var theColorAtTheMouse = ryder.get(mouseX, mouseY);
    stroke(theColorAtTheMouse);
    strokeWeight(stroTwo); //makes a line that changes stroke weight 
    line(pmouseX, pmouseY, mouseX, mouseY); //draws line with the mouse, 
    //so you can paint on the canvas a little bit

}

function drawStar(x, y) {
    textSize(random(20, 70)); //randomizes size of star
    text("*", x, y); //creates object that can be manipulated by position later

}

function mousePressed() { //draws "yum" when mouse is pressed
    noStroke();
    textSize(random(10, 40)); //alternates size of text
    fill("yellow");
    text("yum", mouseX, mouseY);

}

For this project, I instantly though of my little brother: he is always posing for funny photos and I especially miss him right now. I chose to use an asterisk to color in his image, since I think it adds a whimsical touch to the image. I added some randomized tails to each asterisk is order to try to create this oil-painting technique where the image looks like it has some motion to it. I also edited the mouse function so that the stroke is randomized each millisecond, so that it appears like your mouse is a brush that is applying varying amounts of paint. Since my brother Ryder is eating corn in this image, when you click your mouse, the word “yum” pops around. It makes him somewhat of a meme, which is how I see him a lot so it makes sense to me.
