I am new to PovRay and looking for a way to generate random numbers. There
is a clock function that I looked at but is there any other function such as
RND, RANDOM, etc that PovRay has that can generate random numbers? What I am
trying to do is create a pattern on an image using "crackle" that will
change each time I render it. The pattern stays static each time despite
using, "Omega", "Turbulence" etc. Is this something that can be done without
having to setup animation?

Thank you for your time.
Doug
