#73Firefox on Android seems to just be a static image, I can't see any text.

#74Doesn't even show anything on LibreWolf, probably disabled WebGL as usual. I thought it was a nice error screen, but apparently it was intended, just without the text :P

#75You can take TWO screenshots, moments apart, open in GIMP, paste one over the other and choose any one of these laying modes: Lighten, Screen, Addition, Darken, Multiply, Linear burn, Hard Mix, Difference, Exclusion, Subtract, Grain Extract, Grain Merge, or Luminance. https://ibb.co/DDQBJDKR
Yeah if this became popular, we'd have another Show HN for a tool that automated that.

But fun idea, it was nice to see.

#78I don't see any text: just a scrolling down screen of random black/white pixels.

#79This should have an epilepsy warning. Or something of that kind. It certainly made me feel sick.

#80Ha cool! How’s it work?
It's not a great visual, but like this: https://michaelbach.de/ot/cog-Dalmatian/
