Basically I extracted the emojis from my Mac's system font. From there I downscaled them to 64x64 pixels and made them grayscale.
With this set of images I experimented with a few different algorithms. I ended up settling for just a regular ordered dithering (Bayer). But! It still didn't look that good. So what I ended up doing was normalizing the darks and lights for each emoji. This was because some emojis are lighter and darker than others. I wanted to create a uniform appearance for all of them.
So the process was (1) get emojis. (2) downscale + grayscale. (3) normalize tone. (4) dither. (5) then upscale
