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.
