 Here's our program that just continuously draws randomly colored circles to the screen. So in the setup block, we set the size of the display window, and down here in draw, we declare two float variables. X is a random number between zero and the width of the screen, and Y is a random number between zero and the height of the screen. Then the fill is set by random colors, too. And each circle is drawn every time draws run through. All these variables are re-randomized. So this will just keep filling up with colored circles forever.
