Which lead me to finding Inigo's website, and some really informative stuff: http://www.iquilezles.org/www/articles/morenoise/morenoise.htm
Where I found this procedural beauty "Rainforest": https://www.shadertoy.com/view/4ttSWf (This would just be amazing to do in a terrain generator - gives me ideas for a project.)
Even some vague info on continuity in displacement that I was able to refer to elsewhere. Learning a lot, but from no real stepping stone so a lot of back reference and forward reference Lol It's fun though.
