I like to dither images to 2-4 colors and make desktop wallpapers out of them. Here is a collection of my current desktop wallpapers.
IMPORTANT NOTE: While I do modify the initial images, I did not create the initial images for these wallpapers. Unfortunately in almost all cases, I am unable to figure out who made the initial image, so I'm unable to credit them.
Double-imaged anime person with some kanji
Anime person with tan background
Anime person in jacket standing in front of a smiley face
