This project makes incredible artwork with a few simple prompts. Put the red circle in the red box, then put the blue one wherever you want. The ring will multiply and bounce off the walls, making a beautiful pattern. Press the up arrow to show the circles and the down arrow to hide them for screenshots. Press the left and right arrows to control the direction of the circle while it's moving. Happy Patternmaking!
Don't wait for the pattern to develop too much, it'll just turn white.
