The Rendering Equation in Plain English -- make that Math

Ever walk out of a movie and go "How did they do that special effect!?" Well it's not magic, just MATH! (lots and lots of math) Addition, Multiplication, Subtraction, its all in there! Come see how the math is done and how this cool algorithm work when we talk about "The Rendering Equation" by James Kajiya (coincidentally presented first, at a Dallas SIGGRAPH conference - http://www.cs.rpi.edu/~cutler/classes/advancedgraphics/S08/lectures/kajiya.pdf ) You might even see some teapots, boxes, flashlights and puppets.
