In case anyone needs a quick and dirty way to dither images, try `mogrify -path dithered/ -resize 12% -colors 16 -dither FloydSteinberg -modulate 100,200 *` (takes all images in current directory and puts dithered images into a `dithered/` directory)

I chose the resize value to work well with phone image sizes (in my case an iphone 8); I like 16 colors as a good number to get some fun dithering without too much of a loss in quality (though it could definitely be decreased), and the modulate option turns up the saturation to offset the desaturation effect that dithering often has!


maybe use `-modulate 100,180` or something though, I think 200 is a bit too much saturation...
