seed(value) just starts a new stream of random numbers.  That way you can
add new things to your scene that use random numbers without affecting the
previous 'random' numbers.

ie. you start one scene placing spheres randomly with seed(val1),  now if
you go back and add random boxes between the placement of spheres using
seed(val2)
if val1=val2 then the spheres will no longer be in the same random spots
that they were at when they were by them selves, if val1<>val2 then the
spheres will still be in the same spot as they were originally.  Two (or
more) separate streams of random numbers.  (BTW the stream of random numbers
for seed(val) will always be the same no matter how many times you run the
scene).  Hope you understand my ramblings :)
