So, I think there are a lot of uses for this, but there’s a really simple way I found to create a line with shader nodes:

Here is the node:

If you use multiple in sequence you can make some really interesting stuff:

(adding distortion)

I think lightning, rivers, terrain generation in general could really benefit from using this strategically. Possibly introduce some ray marching to make the paths find themselves? Let me know if you guys have any thoughts.
