I was playing with the recently mentioned Rayshade program (really nifty!),
and had an idea.  As I understand it, the Noise() function produces a
random value from 3 parameters, but it's continuous in all directions,
so natural-looking images can be created from it.  How hard would it be
to modify to add a fourth parameter to the function?  I'm thinking a
time parameter could be added, and a surface or texture could be
modified by plugging t into the Noise function.  I imagine this would
lead to a randomly mutating surface as time went on.  Has anyone tried
this?  If someone has (or does), I'd be interested in finding out how
well it worked.

(If you use this idea at siggraph, remember to give me credit! :-)
