Is there somewhere even minimal doc about the numerous included shaders? Sources don’t even have one line of explanation indicating what some of the shaders do.
Ok found that in the examples: LightningJS Examples
Still a very valid point, I’ve marked it in our list. Atleast the code should have some comments to it 
Alternatively we’re working on a shader playground, no ETA yet but that should give some more context about what the different shaders do and how they behave.

Also you can check out some of the shaders in action in the Lightning source code.
