Hi, community!
This showcase based on the examples from my previous post in Resources.
Warning! You’re next to see the worst example of modelling of your lifetime 
(as I’m not a modeller at all 
)
This is just an attempt of modelling, using SDF functions + instancing:
I tried to sculpt a head of an indian chief. Just an explanation for those who didn’t get what they see
Here is a working demo with slight animation:
Another working demo (different realisation of the chief’s nose 
, plus added a music video from youtube, actually, the chief in the scene is because of that music ):
