By the way: the effect I'm talking about is almost exactly what happens
when you apply a normal to the camera (the normal will perturb the rays).
The only difference is that it affects the entire scene instead of just one
object.

  By the way 2: If you bend the objects the way you suggest, your shadows
will be erroneus.
