i played around with the various dithering strategies and i landed on ordered dithering. it may not be as accurately representative and well defined as the floyd-steinberg, but i just love the crosshatch aesthetic 路 3 years ago

for sure! it's not too interesting i'm afraid. it's just using imagemagick under the hood https://github.com/imagemagick/imagemagick

the exact command i use is

convert $INPUT -resize '512x512>' -ordered-dither o2x2,3 $OUTPUT
