This really wouldn’t be that hard to do, CNC machines are essentially step motors on rails holding a tool head. Old (pre-them just being big inkjets) plotters were basically a 2 axis CNC with a tool head that would retrieve, move, lower, raise and replace specially designed pens. My high school had one, a pretty large format one. So you could already pretty trivially have AI gen sketches drawn with actual pens on actual paper if you go find an old plotter, and a CNC painting machine would be about 80% the same thing.
The harder part by far would be building software to convert a JPEG into instructions to paint with and have it look good.








What’s missing is the “camera” panning down to show that road is made of poor men, but that fits because many of them are functionally invisible.
