Greetings!
Last May, "knighty" of fractalforums.com amazed fractal fans worldwide
when he presented a new class of escape time fractals he calls
"Kaleidoscopic IFS." Forum members quickly grasped the concept and
proceeded to create many interesting variants, many of which you can see
in this seminal thread:

Jos Leys then went on to describe these fractals in more detail:
http://images.math.cnrs.fr/Un-ballon-de-foot-fractal.html I highly
recommend checking out the rest of his site if you haven't done so
already; he's done some very cool things.
The theory behind these objects is that all polyhedra have a set of
symmetry planes about which geometry may be reflected. If an iterated
function is reflected, scaled off-center and tested against a sphere,
there will be an emergence of new, often unexpected shapes.
I have managed to make a full implementation of the five Platonic
solids, along with an ad-hoc cavity shader. You can find the scene file
here:

Perhaps you'll find these fractals as captivating as I do :)
Happy Raytracing!
