  I'm amazed. The technical wizardry involved in stuffing this into such a small area of Silicon, then simulating it in a web browser, is awe inspiring.

  At the same time I'm filled with doubt I can get my BitGrid to the same state.

  Author here, and this is how running your design on real hardware feels https://x.com/zzznah/status/1876684831222067350?t=b8-zl-h6uV...

  See also virtual 6502 and ARM1 e.g. http://www.visual6502.org/sim/varm/armgl.html

  How many gates are here?

  Is it near the crossover of where the same amount of logic can implement a tiny CPU which can run a program to generate the same output?

  (I guess not in this case, because it needs to output 18 million pixels per second, and a micro-CPU probably won't be doing that anytime soon)

  This is amazing, I assume the sections lighting on/off are getting electrically activated, but what is this yellow orb slowly moving from left to right near the top?

  Completely wild to me that you are backing out the netlist from the geometry gds.

  It looks visually cool
