A handful of animated wallpapers I made myself in Mine-Imator, available on Wallpaper Engine via the Steam Workshop!
Most wallpapers I make are Ultrawide compatible! If you have a 16:9 monitor, don't worry about the sides being cropped. There's only minor details on the edges for Ultrawide users.
I will add more wallpapers as I make them!
Also check out some of the rigs I used to make this stuff!
