Check out Kwok's Skool of Planetary Design to see how these were made!

David Gervais: I cheated a bit by using Anim8or to render the planet instead of a true 'ray-tracing' program like POV-RAY.

Rollo: here is mine. using the same tools as david. you can see why he is an artist and I am not ;-)

David: ..and here is another planet with a different look...

Katchoo: Here's my masterpiece, known afectionately as the Condiment Planet! Mustard lands and ketchup oceans, as Taz noted.

Suicide Junkie: My Desert Planet, kindly rendered by the good Captain.

Fyron: I made this back in November when Kwok first thought of his Skool. :-)
