I had to think about this one for a little while; but rather than over-strain my
brain, I decided to simply run it, to see what would happen. The result is very
odd: In my 100-frame test animation (pulling only one rand() value per frame),
my moving sphere STOPS moving at about frame 10. I'll try and dissect the
problem here.
Let's see: Since the clock is going 0 to 1, that would put the clock at .10
Then pow(31*pi*.10,10) = 4.2844 X 10^23
(I had to #debug the scene to find that.)
A whoppingly high value, probably over the limit of what seed (or even POV) can
process. The same thing happened during my own trial-and-error phase as well,
several times. Some seed equations just make POV go bonkers.
