> Any idea of how to make lightning between two points?

For animation, I used to draw a random succession of cylinders with no 
shadow and a quite high ambient value
It was between 2 sphere, I drew about 10 cylinders (linked to each other 
with spheres, apex of the 1st one was base of the snd one... and so on) 
and I used random value to jitter those points. After some trys, this 
rendered great as a small electrical arc. I suppose you could use 
somehow the same method to modelize a hige lightning
