is a graphical Perl program, that displays wondrous and beautiful pictures,
that look exactly like the ones produced by the 19th century instrument
called Harmonograph, invented 1844 by Professor Blackburn.

A Harmonograph contains 2 pendulum, swinging with adjusted starting amplitudes 
and frequencies in x and y direction and moving thereby a pencil.
Sometimes the paper is simultaneously rotated by a third pendulum.

This program enhances the original harmonograph by additional options
like rotation speeds, start aplitudes, friction, duration, dot intervals
and different colors and color flows.

The command line version is ment to just produce JPG/PNG/BMP/XPM
with a given set of parameters. (planned)
