This is a demo of Real-Time Mapping of a reflection of a graphic onto
a sphere.  It is system-friendly, it multitasks, it uses an Intuition
Screen, and GASP! -- it's written in C.

It runs a little slow on a stock 68000 machine (5-10 fps) but on any
accelerated machine, speed is decent.  It goes quite fine on a 1200.
Remember, I wrote this overnight just to show the theory... If I wanted
it to be as fast as possible, I would have written the entire demo
section in assembly.  Anyhow, it will run much faster on a machine with
some sort of fast memory (not all CHIP or PSEUDO-FAST).
