Visprint makes cool fractal fingerprint PNG images
based on the contents of any file. The image will
be different for almost every file with even
slightly different contents. Visprint uses the IFS
fractal generation process pioneered by Michael
Barnsley. It is a way to create images that are
self-similar to infinite depths. In other words,
the picture is made up of smaller versions of
itself. Visprint takes a hash function checksum as its input.
