there's an approach missed in that article lying between ordered dither and diffusion approaches - low discrepancy sequences

I'm not sure how much use that is for "modern" systems where blue noise textures are cheap enough but for dithering on retrocomputing devices I find it useful - smoother than random, less expensive than error diffusion.

That page is still up, I linked to an archive because right now for me I see some of the images get blocked at the source.
