Interesting displacement map accident in blender - null point abstract

 Working on "Awkward Thoughts" last night and I was working up a slightly cracked displacement map for the heads, to give them a slightly less 'garden centre concrete' aesthetic ;) In the process I created this monstrosity:

It looks creepy because it's applied to my face, but actually that's not the interesting bit... The interesting bit is that this is exactly the sort of surface I've been imagining for the 'null point' abstract images. I think it's a bit derivative as it looks like an electron micrograph, but I want to explore it anyhow - I suspect it has something to teach me, if nothing else.

I feel like I owe it to Tomgos to go the distance and finish "Awkward Thoughts", especially as it's so close, but after that, I think I might do some experiments with displacement maps, geometry nodes, and non-photorealistic lighting in Blender - this is probably a good example where Blender is actually the natural place to do this - it has all the ingredients built-in, and whilst I'm usually too modest to say it, my Blender skills are actually quite advanced now.
