@jwz error diffusion like Floyd-Steinberg requires too many frame buffer reads per clock, so this is “blue noise” dithering that can be done in one memory access per pixel.
@th I loved Floyd Steinberg's work with Meat Loaf, I didn't know he wrote for Rick Astley too!
@th Reminds me of trying to receive an old analog TV station that is clearly out of my range.
@th Never gonna diffuse error around and quantize you
