I had a request for an electricity effect/ lightning strike and think I found a rather quick and simple way to do it in Inkscape.
With a some additions it turns into a night lightning strike.
If you want to animate these I suggest doing the lines first and altering a copy of the line shape in a new layer [see the animation tutorial for this]. Animate the shape roughly and not too similar. After creating a few variations of the lightning strike start with the conversion to paths.
It’s a lot easier to adjust a few nodes on a line than twice that many or more in a shape.
I hope this quick tutorial is helpful to some.
