IMAGE DESCRIPTION: 
Planetoid with two "spotted" shuttles bearing toward
it from the right.

DESCRIPTION OF HOW THIS IMAGE WAS CREATED: 
For the planetoid, I created two textures (LandArea &
OceanArea) for the land and sea, both with a turbulence
pattern and a colormap of brown and blue, respectively.
I then created three different cloud textures, each with
the same colormap but a different pattern (agate, etc.,
built in to Povray) and combined them in a pigment map for
the layered clouds. I then created a simple sphere with
each texture (land, sea, clouds) mapped onto it.
The texture for the shuttles is a simple white/gray checker
with a turbulence of around 0.8. The shuttle itself was
made with a cylinder of radius 1 and a surface of revolution
object (a cone wouldn't work, no way to get a rounded point)
and the fins are mesh objects with only one triangle.
The "explosions" on the back of the shuttles are halos,
pretty much explained in the Povray documentation... Check
the source for exactly how I did it.
