Hi again,

I made an example-scene which shows the basic use of it.
Sorry for the pseudo-code in my last post, was a bit lazy..

To get the formula to work within POV one has to use
a pattern-function. The cyclic-animation Trick works
by making a Linear-Interpolation between two instances
of the cloud-pattern. The Trick is to translate the second
pattern in such a way that it is identical to the first
pattern when the loop is finished. Thats actually what the
formula does.
feel free to ask if something's still unclear.

Greetings,
Thies
