For this project I chose a picture of my friend Prerana that I took myself last year! Circles appear on the canvas in a random order, and also vary in size because of the randomSize function. In addition to the points, if you run the mouse over the canvas, her initials appear in the color of wherever the mouse position is located based off the image pixel color.
