You can change the angle and speed at the top. If you want to hide the balls, angle variable and the speed variable, press the down arrow. If you want to see the balls, angle variable and speed variable, press the up arrow. It is default to show them all. Some angles & speeds I recommend are: Angle 7, speed 2 Angle 31, speed 10 If you want different pen sizes, I recommend: Pen size 10, angle 10, speed 2 Pen size 100, angle 10, speed 2
I used a book to help me with this project.
