Unordered dithering gives better form shading as there is no structure overlaying the shape,I would love to see "Recursive Wang Tiles for Real-Time Blue Noise
ps://www.youtube.com/watch?v=ykACzjtR6rc" combined with that technique
You don't need to make things all that difficult just to get some random looking blue noise though. You can get some pretty reasonable randomized ordered dithering by just rotating the 2x2, 4x4, 8x8 blocks of the bayer matrix randomly. Though this makes more sense if you view it as adding octaves of the 2x2 bayer matrix together randomly.
