I remember coming across various wallpaper worthy images from Is This A Zombie? and adding them to my collection.
Seeing my desktop select this one of Eu out of its random rotation of wallpapers, I was rather surprised how well this one works on a 1080p display.
These days most of the wallpapers I've collected over the past eon, I see on my tablet screen. Because that's the computer I use most often. At work, usually SFW stills are statically set. At home though, I still keep my PC's set to a random rotation.
