Color transform II
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 finding the point on the screen where the parameters don't change. Then move the mouse pointer slowly away from that spot. Try moving it in different directions, for example, first move it vertically away from the spot, then horizontally, then at an angle.
