Click the green flag and watch the spiral spin! Press any key (or the background if on mobile) to clear the screen. A few keys will change the angle and/or speed and/or pen size of the spiral. Try to find them! You can also manually change the angle, speed, and pen size via the sliders. You can also click on the ball sprite to change it's color, and the up and down arrows to show or hide the ball and variables. Have fun, and see what you make!
