I am pondering a different approach: * Use error diffusion dithering in screen space * Generate motion vectors for every pixel from the previous frame Now, to make the next frame: * Take the previously displayed (dithered) image and apply the motion vectors. * Now use that as the threshold map to do error diffusion dithering on the next frame. The threshold doesn't really matter for error diffusion dithering - since any error will be propagated to the next pixel. However, if you use a previous frame as a threshold map, it will encourage pixels not to 'flicker' every frame.
