I seem to be suffering a bit of creative drought.
I had no idea what to POV next, but when I saw Gail Shaw's post I thought
"ooh I'd like to do a space ship!", then I saw Skip Talbot's post and
thought "ooh I'd like to fake a nebula in 2D on the sky_sphere". So in
addition to ripping off their ideas I also decided to rip off the films 2001
and Sphere. The only slightly original idea here was the black hole, though
it's no coincidence that the idea occured after I saw the current 3Drtc
topic: "the black cloak".
Uh... anyway... The cool black hole effect is achieved with a refractive
object shaped so that it has no refraction at the edges when viewed from the
camera's point of view, effectively making it a 2D distortion. I then use
several such objects at different distances to create the event horizon, the
"sucking" effect, and the smaller distortion on the ship.
Other than that it's all CSG on the spaceship, and the nebula, stars, and
sun are just a layered pigment on the sky_sphere.
comments? questions?

Really?? :-)

I am not sure I understand the technical part, but it is very clever
nonetheless.
To make it even better: black holes spin usually, dragging light with them.
Could you simulate that distortion too?

Very nice.
I'm not sure about the distortion ring. To me it looks like the black hold
is surrounded by a torus of glass. The other effects are really cool.

quick! Someone hijacked Tek's news.povray.org account! :))
way cool, Tek! Of course, a real black hole doesn't actually sucks things
ordinarily orbiting them safely away from the event horizon, but still...

Mmm, I like it.
The ship itself seems a bit bland, but the rest of the image is really
quite good.

Well the sucking effect is created using a funny shaped lens, but as far as
I know it's impossible to make a lens that will rotate things...
Although maybe if I stick a radial normal on there... hmm...

It's actually more of a cone shape, but it is very much a glass-like
material. I'll work on it a bit more to make it less obvious...

You may have a look at spiral normals, it's more evocative of a rotation.

The ship seems to be sitting awfully close to the event horizon.
It would probably need to orbit at relativistic speeds itself ;)

Swirly effect! I added a radial normal to my distortion effect, which is
ramped up towards the middle of the effect to things get swirled more the
closer they get.
