Gentle Rev users,
If you have ever watched any of the History Channels exposés regarding
this topic, the Las Vegas gerús have come to the conclusion that there
is no such thing as a random number generator, or they would be using
it to foil "us". Read all you want, but it is a waste of time to
expect that you will ever come up with anything that is truly random.
In my personal use, I have followed the users mouse clicks, used the
last one to plug into a pretty exotic personal equation that spits out
a seed number for use. Since the mouse clicks of a user are pretty
much uncharted, except for being limited pretty much to the
screenrect, a fairly high degree of unpredictability should ensue. I
haven't used this with Rev, so I'm not sure how well one can hide the
personal equation.
My 2 centavos,
Joe Wilkins

It depends of what you use to reset the randomSeed. Some papers
(reference burried to deep in my memory to be retrieved) suggest to
generate an array of random numbers at start, and then to reset the
seed each time it's needed with one of these elements, the index
being randomly choosen. And the first x random numbers you draw are
used to replace the array for the next time...
But that is only a sophisticated kind of reshuffling.
I just looked at the Web of Science for "Random number generator":
1252 papers. I do not think there is ONE obvious solution...

Me too. Wouldn't it suffice to do this before each
run?:
set the randomSeed to random(4570422)
In theory, that could result in the same series of
random numbers multiple times, as the first random may
start with the same randomseed as another, thus
resulting in the same random first number, and thus
the same second number and so forth.
I'm pretty sure I'm missing something that will make the dim light
in my head brighter.
It would seem that resetting the randomSeed each time you use the
random function would only have a 1-in-4,570,422 chance of getting
the same seed as the previous run, no?
