What I'm looking for are some cloud-like formations for
close-up shots...e.g. flying over/through cloud tops.
Do these exist already anywhere or do I have to rt proverbial
fm and make something myself?

Holy neat!

As an active skydiver, I find these cloud images very
exciting.  Rendering makecloud2_demo_rain, it does some kind
of interlaced draw.  I'm used to my renders starting from
the top and drawing line by line...

What makes the scene draw giant boxes first, then slowly
shrink the boxes as it renders?

I can only assume it's one of these?  I looked them all up
though, and still can't figure it out.

global_settings {
    assumed_gamma 1 // use a higher value if necessary
    max_trace_level 250
    #if (RadOK=1)
        radiosity {
            count 10
            recursion_limit 1
            low_error_factor .5 
            gray_threshold 0.0  
            minimum_reuse 0.015 
            brightness 1
            adc_bailout 0.01/2
        }
    #end
}

Sorry, egg on my face...

Until 10 minutes ago, I didn't know what radiosity was, nor
that I wasn't already doing it.  Heh.  I read about all the
settings for radiosity, but failed to read the description
of radiosity itself!

Probably the radiosity (if I understand the effect you're describing).
