FRACTINT plots and manipulates images of "objects" -- actually sets of
mathematical points -- that have fractal dimension.  Using integer math,
these sets of points are generated by relatively simple calculations
repeated over and over, feeding the results of each step back into the
next, something computers can do very rapidly.  FRACTINT lets you zoom
into a small area created by the calculations to reveal intricate
detail, from which you can assign colors to selected points and
"animate" the images by quickly shifting those color assignments.

An advantage of FRACTINT over other fractal graphics programs is that,
as formerly mentioned, it uses integer math, rather than the
floating-point calculations. That means that you don't need a math
coprocessor chip (aka floating-point unit or FPU), though it will
recognize and automatically use an 80x87 chip if it's present.

FRACTINT works with many adapter and graphics modes from CGA to the
1024x768, 256-color 8514/A mode.  Even "larger" images, up to
2048x2048x256, can be plotted to RAM, EMS, or disk: this bypasses the
screen and allows you to create images with higher resolution than your
current display can handle, and to run in "background" under
multi-tasking control programs such as DESQview.

The program was born fast through an experiment in collaboration by Bert
Tyler and many volunteers.  The authors of this public domain program
encourage further contribution of ideas to make FRACTINT even better
than it already is:  "speedy, versatile, and all-around wonderful."
