Very nice :) Some modyfication of sky_sphere / bozo probably? Will source 
code be available?

thank you :)

> Some modyfication of sky_sphere / bozo probably?

a large sphere with a bozo pattern multiplied with another slightly translated
(in the opposite direction of the light_source) bozo pattern.
not perfect at all, but I think it can be useful for animations, where you don't
have the time to notice the faults :)

after I clean it up :)

Impressive... so they wouldn't take much longer than an hour on my 
ancient rattletrap under Windoze 98 ;-)!

Do they cast real shadows?

it's just one sphere with only one texture, so it will probably not take any
longer than a few minutes :)

They do cast shadows, but they're not 100% accurate
