Sounds awful, I don't know why one would ever want that.
That being said:
It warmed my nerd heart that the first thing I spotted in the mpvpaper repo was an animated Steins Gate background.
If you run KDE Plasma as a Desktop Environment:
If you roll with Hyprland compositer for Wayland, I think it can do wallpapers.
I know I've seen 8/16/32bit videogame/anime sprites on some peoples setups.
Shameless self plug for a program I don't even use because as cool as shaders for a wallpaper sounded...I prefer a nice anime one XD. https://hg.sr.ht/~scoopta/glpaper
I use swww for wayland. I've seen quite a few others with similar setups as well, though I don't know how you do it on the Xorg side of things.
Are you new to Linux? I'm not trying to be mean, but I just want to know so it'll help me better approach the situation.
Wayland is a replacement for the X11 window system protocol and architecture with the aim to be easier to develop, extend, and maintain.
Wayland is the language (protocol) that applications can use to talk to a display server in order to make themselves visible and get input from the user (a person). A Wayland server is called a "compositor". Applications are Wayland clients.
As in video wallpapers? Sure. KDE Plasma for one lets you install a bunch of wallpaper plugins ranging from video playback to live computed shaders and everything in between.
swww is a daemon for wayland that lets you change your wallpaper in real time and can display moving Gifs and a ton of other formats (everything you'd expect) plus some free and OSS image formats like the ones from suckless. It also has these sick transition animations
