Cool 3D With Graphing Calculator

From Gary Johnson, "I was playing around with the Graphing Calculator and discovered that you can paste a graphic onto a 3D surface. For example, graph the equation Z=sin X and then open up Quicktime and copy your an image from your favorite scene from the Phantom Menace trailer and paste it into the Graphing Calculator. It even shades it for you. Pretty cool...and best of all it's FREE. You can even export it as a Quicktime movie." [Graphing Calculator comes with recent Mac OS versions. I'll have to try this--Bill]
