IMAGE DESCRIPTION:
 
Whoever thinks electric light is an invention of man, may think again - 
our night skies are lit up by electric light not even today fully understood by man,
and - ironically - free of charge.

DESCRIPTION OF HOW THIS IMAGE WAS CREATED:

The road, the clouds and the explosion smoke are isosurfaces with noise3d functions.
The lightning is a hollow cylinder difference with a partly transparent agate color map. 
The street lights are all CSG.
The stars, the explosion glass shards and the wind-swept street lights were positioned 
with random function loops.
The cloud underside lighting is from a single light source (instead of one for every lightning bolt),
for render time reasons.
