TechnoRobbo's Tesla Coil Plugin

 

A Simulation of an electrical arc and the arc breaking down.

Lots of adjustments so you can go from Realistic to Comic Book style.

Oh man I have been waiting for someone to make a plugin like this. I am definitely going to play with this after i eat something,maybe for the rest of the night,lol. You da Man!! 

[Ego Eram Reputo]

That's a pretty cool effect.  +1 for the source code which should be an inspiration to aspiring plugin coders out there.

You could have used this: Lightning.
