Hi Michael,

four sources come into my mind -

using camera with normals to distort an image as a whole are rare, but look at
David Morgan-Mar  Monet's Garden in Giverny
http://www.irtc.org/ftp/pub/stills/1999-12-31/dmmonet.jpg

two sources distort images via post-processing

Tor Olav Kristensen  Source code for "Using functions to distort images"
http://news.povray.org/povray.text.scene-files/message/%3C4470f87e%40news.povray.org%3E/#%3C4470f87e%40news.povray.org%
3E

Samuels code uses normals and dispersion, but not an ior different from 1.

and the fourth source uses ior 1.4 and dispersion, but not normals - Tekno
Frannansa  photo-style short code

E

Tek used some more effects in his winning IRTC entry Elements, but again - no
normals - http://www.irtc.org/ftp/pub/stills/2005-10-31/elements.jpg

So, your trick is imho new.

By the way, thanks for your nice gallery. My personal favourite is "growth", but
most of the others are very good too. The minimalistic style of your gallery
reminds me a bit of Margus Ramst`s homepage (
http://www.hot.ee/margusrt/eng/main.html ).

So, keep on poving...
