I used ordered dithering in my ZX Spectrum raytracer (https://gabrielgambetta.com/zx-raytracer.html#fourth-iterati...). In this case it's applied to a color image, but since every 8x8-pixel block can only have one of two colors (one of these fun limitations of the Spectrum), it's effectively monochrome dithering.

This is really nice work, as are the other posts.

If the author stops by, I'd be interested to hear about the tech used.

In chrome it says "Loading assets, please wait..." and hangs. but it works for me in firefox
