(Minecraft) Spreading Lava Concept

This time I didn't reupload, but instead remade. This is the first time I've uploaded something that's been on nowhere else but Vidlii before.

The purpose of this video is to show off a module I came up with one time that makes lava spread like it did a long time ago, for the sake of map makers. It can massively aid the creation of maps about rising lava or something modern but similar to things like Minecraft Classic's "Lava Survival" - all in a mere <90 character command. Obviously, you're free to use this, but put it in a repeating command block or it won't work.

The old spreading lava video was - by my standards - full of unnecessary information and not good enough. So here's a short, higher-quality version with a better score.
