Use the sliders to adjust the angle, speed, and color of the pen! Right arrow to choose the color of the spirals! (lol change pen change to ten and hold on right arrow) Press space to clear the spirals and lines. You can go inside to change the pen thickness :P Press 1, 2, 3, and 4 for pre-made spirals! 4 is the coolest :)
