Just click the green flag, and watch the ball bounce around. It also changes speed and colors. This project was updated on 21 August 2019. You can now change the speed of the ball, although by default, it still accelerates to 25 steps per frame. The ball now leaves behind a trail effect as it moves, and I've also added a little check for the bouncing so that it should never bounce from corner to corner boringly.
This expands on showing some of the "how-to's" I've come to create. In addition to color changing and noise, I've made the ball get gradually faster before reaching terminal velocity. The ball also bounces off the edges, a little unevenly, but still a good way of learning.
