Thanks. As I'm beggining to actually write code (thanks to QTPovEditor), it
began as a test with triangles, later came the cylinders, the moon and
finally the ladder (an old object from Leonardo's image).
It is also a test with lightning.
I mean, nothing was planned.

The moon has an image map only in the pigment statement. I have tried using
a bump image map in the normal, but I liked more this effect, as the moon
we see actually, without a normal map (at least me, I wear glasses). Still
it's a WIP, maybe in the end with an isosurface... but I still have to
learn it.
The image maps I have are 2000x1000

Well, you can simply animate the texture.
