It was just an example. Materials are a complex beast and not easy to wrap one’s mind around.
Considering marking the vid you linked with a timestamp so folks know precisely which effect you’re after. As currently…
something
like the third part of the video with
the colored drawing of Claus
I don’t know who Claus is and refuse to watch 20mins to find out ;p And there seems to more than a dozen of different distortions in that trippy thing 
This way you’re more likely to get a nuanced, accurate answer rather than a generic vid I linked.
