A ball that bounces around, spitting out other balls that grow progressively smaller and change color. This was done through the use of an array. I feel this is a more in-depth example of array usage than a large amount of randomly generated circles.
This is an example of an array of objects created via a class, and represents the class component of the portfolio. A circle class makes circles with random color, size, speed, and direction that bounce off of the sides of the sketch.
