The solution I'm currently investigating is :
1) I start with a still image (multifractal or fractionnal Brownian motion)
and then
2) I add 2 sine waves of different Ampitude, Frequency and Direction and
then
3) I add a Three (x, y (or z) and time) dimensionnal correlated noise (don't
know yet what will be the final form)

The sample I've posted is made of Part 2 only (the smoothest ocean possible
!),
The code for part one is written and working (!!!?)
The final idea for part three is in my head I just have to squeezzzzzz my
brains to take it out !

Of course I'm interested in your Code, I hope I will come with an idea for
your point 2, because it is my current concern
