Original Description:
This works like the cool toy you probably used to have (or still do). You spin the little gray knobs to make your own pictures. The left knob draws up and down. The right knob draws left and right. Just click and hold down the knob with your mouse button, then drag the knob in circles.
You can click where it says Random Sketcher to have the computer do the drawing for you. To clear the screen and start over, click Random Sketcher and then click Manual Sketcher again.
