Trying a 2D Markov chain with an image. The source image (left) is sampled as 3*2-pixel windows. The output image (right) is randomly generated pixel by pixel, first right, then down, by choosing from the likely colours to appear at the bottom right of the current window.

The program falls back to a hard-coded colour (here, light grey) if the previously-generated window doesn't match anything in the input data. (The program isn't ready for release yet.)

Dang, I've been negligent about sharing my recent work. To start off, here's the first of a three-parter. It goes into detail on what Markov chains are, touches on Markov Chain Monte Carlo, and then how large language models relate. It ends with an insight into how LLMs work that I haven't seen discussed elsewhere:
