This is an update approach to the previous post that modifies the pre-processing step. This version uses Bayer Dithering to produce a dithered monochrome image. The implementation is based on this Shadertoy example of Ordered Dithering.
I came across the great Ditherpunk post again today, and had to try my hand at a brief implementation. The pre-processed images now contain much more detail, and the resulting Game of Life is different.
