Change the Angle and the Speed using the sliders or pressing the buttons next to the sliders. Press space to clear the pen (if you wanted it). Up arrow to show the ball and variables and variable boxes. Down arrow to hide the ball and the variables and variable boxes.
I recommend these settings: •Angle: 68 •Speed: 2 •Angle: 49 •Speed: 5 •Angle: Working on it... •Speed: Working on it... •Angle: Working on it... •Speed: Working on it...
