The following code plots a series of lissajous and animates them.
It is possible to see the resulting figure in about eleventy-
two different ways: cylindrical or flat, rotating or oscillating
about a horizontal or vertical axis, moving toward you or
away, moving to the left or to the right, or just wobbling.

I call the program LLL for Lincoln Lab Lissajous since the lissajous
is our logo.  To work it, download or enter it and press the GEN
button.  It will run for a few minutes and beep when it's through.
Then press the SHO button and watch.  Finally, press any key to quit.

If you have trouble seeing the image in different ways, try focusing
on a single intersection in the plot as it moves.  Pretend that the
point is in front as it moves in one direction and in back when it
goes the opposite way.  Once you get that to work, reverse directions.
