I prefer "Psycho Graphics". Are there any other suggestions? 
(It may be better to discuss the terminology well in advance
 than to suffer from bad mistakes, such as "distributed ray
 tracing", in the future :-) )

Anyway, critisism against physics as the sole base for realistic 
visualization sounds justified. Research in this field has heavily
concentrated on illumination models and geometric modelling. Some
work has been done on slightly more advanced camera models than the
standard "pinhole" (f.g. distributed ray tracing). Our relationship
with the camera (and the perspective projection) may well resemble
the relationship of early car-designers and horse-driven carriages.
