Color transform I
There are two parameters controlling the colors. By moving the mouse you can change them. Moving the mouse vertically controls one of the parameters; moving the mouse horizontally controls the other. See if you can make the animation stop by getting the mouse pointer in the exact center of the screen. Then move the mouse pointer slowly away from the center of the screen. Try moving it in different directions, for example, first move it vertically away from the center, then horizontally, then at an angle.
