I've just found where I saw a similar technique, it's a remix of: d/17222 by u/tomxor , and my comment there was "Please create more like this."
u/Joachim

u/rodrigo.siqueira LOL what were the chances!? Well, I guess that’s proof that people like them!

bump mapping remix

u/Joachim

Really nice #lighting
u/@noel

Beautiful. I need to dig into this, to understand how this actually works.
u/rodrigo.siqueira

Wow! Replace X^Y with X|Y to generate Sierpinski triangles. Replace Math.min with Math.max for a more dramatic effect. Remove |0 for improved golfing (a minimal visible effect on top alignment). Replace "t*1.2" with "C(i+t)*6" for the "water effect".
u/jellyedwards

Wow that's amazing!!
