How to make procedural lightning bolts?

I'm looking for a way to create procedural lighning bolts similar to this: http://forum.unity3d.com/viewtopic.php?t=5897&start=28

Any ideas on how to achieve this? Maybe Eric5h5? ;)

Have you looked at this source code, provided directly by the good people that make Unity?

http://unity3d.com/support/resources/example-projects/procedural-examples

There's a procedural example in there for a lightning-like effect - it even moves around at runtime on its own.

Eric's post said he'd release the source code on the Wiki, but it looks like he never did (I searched for lightning). If you simply wanted to ask him to release the source code, you should have done it in the forums instead of posting an entirely new question on an entirely different site. :P
