Oh, I finally did see *one* little flaw, but I had to look hard to find it!
Slightly upping the samples count got rid of it.

It occured to me that, the way his code is set up in the makecloud1_demo, there
is only one real media cloud definition, duplicated a bunch of times in his
#while loop.  Thus all the clouds automatically have the same # of samples.
I'm willing to bet that if each cloud had a random #, there would be visible
box intersection lines all over the place!
