I've been looking at lots of pov images lately and I've noticed a LOT of
images that use a so called Stacked plane clouds system. Something like
stacking a bunch of planes with the same or similar cloud pattern on top of
each other. How is this done? because the results look awesome and are
supposedly pretty fast. Is their a tutorial on it?

Thanks,
Corey

The technique you're asking for is pretty simple
and you've already named the basics of it yourself.

There is a short explanation to be found at
http://www.ignorancia.org/index.shtml
(under techniques -> tips&tricks)

You can find another short explanation on
my homepage (URL below) in the gallery.
The image "Worldbowl" (newest image as of
right now) uses this technique twice, you can
look at it there and download the scene-file
as well (as a ZIP).

Hope this supplies a nudge in what directions
you should go...

The technique uses a bunch of partly transparent planes with 
double_illuminate (you need either MegaPOV or POV 3.5), with the 
completely transparent parts being sky and less transparent white parts 
being clouds. It basically simulates an unjittered sampling of media.
It was originally meant as a replacement for media clouds, but MegaPOV 
and POV 3.5 have new media sampling methods that make it much less 
necessary, though it is still useful sometimes.
