For anyone that wants to try Yliluoma's dithers for themselves, I have created the only interactive version that I am aware of, as well as the only GPU accelerated version at https://app.dithermark.com

Ooh, I'd read this article before, but didn't realize Joel Yliluoma is Bisqwit. He has a YouTube channel on technical topics including: making your own terminal emulator, NES emulator, 3D engine, Tetris, programming in raw assembly. https://www.youtube.com/c/Bisqwit

I just tried Yliluoma 1&2 on video it right now, and it does about as well as Bayer ordered dithering, since it is a variation on ordered dithering. You can try it yourself, since I built an app[1] that includes the Yliluoma 1&2 dithering algorithms, and supports video.
