... lots of free spherical science textures at

Good thing I did not yet join the ranks of the physics simulation
crowd ... it would be too tempting to play with science marbles ;)

BTW, is there a way to illuminate scattering media WITH radiosity?

I think "media on" only controls the effect of media ON radiosity.

You used to be able to do it with high ambient values, but ambient is disabled
when radiosity is on, now... there is that emission keyword in the finish block
though...

*goes off to experiment*

NO, radiosity can not illuminate any media.
But, scattering and absorbing media will affect radiosity rays passing 
through them even is you don't use media on, and can cause apreciable 
shadows if thick or dense enough.
