  So I am GUESSING what is happening here, if you want to know why Pov
is crashing on you, is that you have your camera location at
(clock*clock*clock) and the scene is starting at clock = 0. This places
the camera then at xyz = 0.
  You end up with a divide by zero error when the camera location and the
look at are at the same location. Before you can get an error warning
from the program the system steps in and issues an invalid page fault
instead. You could avoid this with something like:

camera_location = (clock*clock*-0.000001+clock)* FinalRestingPlace

  That little amount of offset from the origin is enough to avoid the
divide by zero problem and everything becomes one with the universe
again.

  But then again I might have read one too many messages on this server and
I have gone totaly daft. You make the call.
