this came up from a google search:
http://news.povray.org/povray.text.scene-files/thread/%3C3aed8503%241%40news.povray.org%3E/?mtop=12

maybe it could be modified to connect to a certain end point.

Any searches through the web interface of the povray newsgroups for
"lightning" only shows that people mispell "lighting" as "lightning" way too
much to make "lightning" a useful search term.

so i give up. my two cents are, it seems lightning is more tree-like than
spline-like so i'd go with a fractal-type method. Plus, if the lightning is
way off in the distance, sphersweeps are unnecesarily slow. some combination
of cylinders and cones with spheres connecting them would be faster.
