The breakout mod I created starts with a single white ball bouncing around the screen. As it hits a brick, it spawns another ball and inherits the brick color. The brick then dies and becomes a mini ghost brick that follows the paddle around and haunts it. If the ball hits the paddle, it loses its color and turns white as it bounces back. The bricks eventually regenerate with a random color and after a few seconds, there are so many balls on screen that it turns into a piece of generative art.
