For come context, this uses a technique called CPPN’s (compositional pattern producing networks), where the inputs are (x, y, sqrt(x^2 + y^2)) and then there are several neural net layers with different activation functions and randomly initialized weights. It actually resembles the optical physics of light reflecting through glass (which explains why it sometimes looks like light reflecting through a gem).

Is this related in any way to how Nvidias NeRF's work?

Yeah, if you look at the original NERF paper (which is not by Nvidia btw) they cite CPPNs as prior work.

At the risk of sounding like an idiot. What even is this? Is there a purpose? It looks just like random pixel generation to me. There is no explanation anywhere I can find on a "purpose" or "motivation".

Who says art needs a purpose?
It makes abstract patterns, some of which you may find pretty. It’s similar to other algorithmic art dating back to the 60s.
