boing - draws a bouncing ball like the ancient Amiga demo

The boing program draws a bouncing checkered ball on a grid.
This 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.) The boing ball was briefly the official logo of Amiga Inc., until they were bought by Commodore later that year.
With no arguments, this program looks a lot like the original Amiga demo. With "-smooth -lighting", it looks... less old.
