No worries! Yes, I discovered/created the MNCA technique myself.

As for what they are, they're basically a bunch of convolution operations stacked on top of each other, but the reality is the techniques are varied and technical in ways that are hard to describe.
I came up with them mostly because I was bored and wanted to try and do something interesting and emergent, and just started trying harder and harder to cook up more and more interesting patterns. Didn't really understand them or aim for anything specific. My own personal dopamine farm, if you will, haha.
Eventually I ended up writing Vulkan GPU render engines to get more power and more time to run more complex patterns, and things really took off from there!
