I think the thing that's lacking from these Blue Marble attempts is that the
glass has no depth-based colour change. Most coloured glass gets darker as the
depth increases. Finding a way to do that which still renders fast could be
tricky though... hmm.

No closer to the target, but now it spins. Enjoy.

fade_color [some colour]
fade_distance [some value]
fade_power 1 //linear relation, real world value. Suqare (2) is for light_source
fading.

I don't think this would produce results close enough to the NASA example
though. I'm thinking media might be a better choice in this instance, to give
it more of a "dense" look.

If you need the tinting to be more intense, you reduce the fade_distance. You may also
increase the
fade_power.
