You mean like this?

light_source {<5,5,5> rgb <2,1.6,1.2>}
light_source {<-5,5,5> rgb <.6,.8,1>}
camera {location <0,5,5> look_at <0,0,0>
  normal {radial 40 frequency 3 rotate <60,0,0> translate <-0.6,-0.6,0>}}
plane {y,-1 texture{pigment{checker color rgb 1 color rgb 0}}}
sphere {<5,0,5.25> 1 pigment {rgb .5} finish {reflection .6}}

Look up the camera definition in the help file - there are different projection
types (like fisheye) as well as the ability to apply normals to the camera lens
(as in the above example).  I'm sure there are endless possibilities for what
you can create using these :)  For example, you could give an image an oil dab
painting look by using a very small and light wrinkle normal on the camera.
