The applet above will allow you to explore persistence of vision yourself, and perhaps allow you to understand it a little more
clearly. The image above of the rotating triangle is made up of 3 separate images. As you watch it rotate, the animation is
going by at frames per second. Now click once on the image of the triangle. Now that the applet is primed, using the "up" and
"down" arrow keys on your key board you can control how fast or slow the animation runs at. By pressing "down" many times
you can slow the animation down and see the three separate images that make up the animation. As you press the "up" key
the animation begins to speed up. If you keep pressing the up key there is one speed where the animation seems to flow
almost seamlessly. If you make the animation go any faster the flaw in our eyes known as persistence of vision blurs the
images together so much that you begin to see only two images.
