A sort of abstract picture for Friday. Functions
are used to do a circular inversion transform on an image
map pigment. This is similar to the effect I saw once in
a photoshop plugin.

Nice.
Wings3d? Maybe not. After playing with Wings today, I think
there's a function that uses a background(?) image - and then of
course, it's how you manipulate that background image...

It's actually done entirely within POV-Ray as a
function, applied to an input pigment (which
happens to be an image map in this one instance
but could be any pigment, like a checker). No
intermediate files (pictures, include files) are
needed.
See, the truly wonderful thing about v3.5 is you can
go from pigment to function and back again. You
can really do some damage now. :D

That's fantastic!
I've always wanted to figure out how they do that... *sigh*

You might want to try:
http://mathworld.wolfram.com/InversePoints.html
That's how I was able to figure it out. That site is
a must for POVers. It really helped when I was
re-learning trigonomitry for some renders.
I am also posting the source in
povray.binaries.scene-files. Subject will be
"circle inversion"

The Kai's Power Tools filter in question is called "Vortex Tiling". Your rendition
of it is reasonably accurate.
