The Showcase gallery exhibits fractal art created
with Ultra Fractal, each time focusing on a
single fractal artist. This time, the featured
artist is Jos Leys, a fractal animations pioneer.
In his own words:
I am a mechanical engineer and have always
had an interest in
mathematics. That is why, for over five years
now, I enjoy working with Ultra Fractal mostly
because one can write one's own algorithms.
I am always on the look-out for mathematical
theories that can produce images that no one
has ever seen before. Translating these into
Ultra Fractal code is my main hobby. I am 53
years old and live near Antwerp, Belgium with
my wife Gilberte and our two cats.
(Note: Most of the formulas used by Jos Leys
are not in the public domain so you should not expect to be able to
recreate these images immediately. However,
Ultra Fractal users have access to a very large
database of public formulas,
of which some are capable of producing similar
results.)

A Kleinian group, a very special kind
of fractal...

This was an exercise in the presentation
of 3D objects...
Some of the things I have programmed are 3D,
so they beg to be animated for a really good view.
It was possible to make animations using older
versions of Ultra Fractal, but it was quite cumbersome
and required manipulation of parameter files in
a word processing program. The built-in animation
features of version 4 make this obsolete, and
animation is now very easy!
