Unless you can apply the non-linear transformation on a per-object
basis (so that its shadow and its reflection/refraction on other objects
etc are also transformed correctly), the effect is rather useless
(except for making some abstract art).
Also, I would like to know whether the rays used to render those images
were really curved or if they were just straight rays transformed on
a non-linear basis (similar to what eg. the normal{} block in a camera
statement would do).
