This bouncing ball is a clone of the first graphics demo for the Amiga
1000, which was written by Dale Luck and RJ Mical during a break at
the 1984 Consumer Electronics Show (or so the legend goes.)

This looks like the original Amiga demo if you turn off "smoothing"
and "lighting" and turn on "scanlines", and is somewhat more modern
otherwise.
