I)
For my fractal animation ("Warp's Julia Island Forest in Winter,")  I
explored 11.85 orders of magnitude in camera angle. My variable for the
camera angle went something like (roughly from memory):
   #declare angie=1.2*10^(1-11.85*clock);
Then I could set up a zooming animation, just debugging out the value of
angie with each frame.

II)
Another application involved using the cells pigment in an isosurface to
make a city.  The max gradient value has a huge effect on the "quality" of
the image (the diffuse==0 problem for step functions in isosurfaces).  I
set up an animation with a variable  for max gradient called
   #declare maxie=1.2^(33*clock+1);
and added a text object to the animation  (roughly from memory)
   text_object{"timrom.ttf",str(maxie,3,1),1,0         //blahblahblah
The result was my own tutorial showing me the effect of the max gradient on
the quality of the image.

Oops--this should have gone in p.u.p.  :-|
