    Clifford Pickover's book, "Computers, Patterns, Chaos, and
Beauty" has many beautify little programs to show off your computer.
This is another one that I have plucked from his book, and have
programmed to allow others to see some really interesting patterns.
These patterns appear to be Moire ones and are calculated by
determining if a bit is set in the resultant product of
multiplications.  Pickover never mentioned the use of non-integer
values for this type of function, but they work as well as integer
values, and give lovely pictures.
    What this program does is check a bit in a byte, and if it is set,
then put a dot on the screen.  The function is just the pixel number in
the x direction times the pixel number in the Y direction times a value
that you choose.  You can also select which bit in the product will be
looked at.  For the most interesting pictures, a bit value of
12-20 is good, and a multiplication value of 20.0 - 200.0 is also good.
    This program will work in all of the ST and TT resolutions and
will use the math co-processor if it is present in the TT.  The
program is very easy to use.  After the title screen, you will pick the
two factors that will generate the pattern.  After the screen is
generated, pressing any key will allow you to make a new picture or
quit.
    I hope that you will find this program enjoyable, and fun to play
with.  Mathematics is not a dull subject where you learn all kinds of
boring manipulations, but a visually exciting area.  This is one of a
series of graphically interesting, mathematical programs.
    If you would like to see the source code for this program and the
others that I have generated, you can send me $5 and I will send you
the Modula-2 code.
