This is an image I've been working on (unfortunately not for IRTC). Its 
focus is (obviously) hot air balloons (currently one). The background 
environment is not rendered at nearly the best settings I have set up, so 
try not to comment on that part. I made all the isosurfaces used here from 
scratch and I still need to make a burner and maybe passengers. Comments 
and advice are welcome!

I think the current background settings give it a nice cartoony style like a
story book. The sky and colors of the balloon help to. Only problem I have
with it is the rad artifacts near the bottom of the balloon, but still a
very nice image.

I never thought of that before... I'll try and maintain this look in the 
final version. Thanks for the comment!

It looks like a noisy isosurface with a slope-dependant texture - which section

of the manual do I have to look up to understand such textures?

check out the slope pigment (6.7.11.30) and use it in a texture map

texture {
    slope y
    texture_map {
        [0 pigment {}
            normal {}
            finish {}
        ]
        [1 pigment {}
            normal {}
            finish {}
        ]
    }
}

have fun

My first attempt at a landscape with slope-dependent textures -
heightfield made with Jon Beale's HF Lab. Nothing really
spectacular, I used a slightly turbulated gradient y texture map
containing in itself two bipartite slope texture maps and one
simple texture...

Thanks, Kevin... be prepared to lend your name to an asteroid/crater/ice
fracture in my Shams stellar system one day!

Perhaps I should use isosurfaces rather than heightfields in the future,
to get rid of the griddy texture borders, as with the
boundary between dry pastures and desert in the lower left...

What I usually do with height fields is interpolate them in a paint 
program, then render with smooth turned off. This eliminates the artefacts 
but the resolution needs to be very high.
BTW, a higher quality landscape for Balloon Trip is on the way but it's 
been rendering for 4 days at only 640x480 0.3AA. Looks like multiple media 
radiosity and isosurfaces don't mix very well...

Does that mean you apply a blur on them?

Basically, but not enough to destroy any detail.
