24wallpapers is another website with free wallpaper with over 20 categories to help you find something you'll like. One section is for "other" wallpaper, so there's surely lots to pick from here.
The 24Wallpaper home page shows which search terms are trending this week, showcases featured wallpapers and albums, and lists all the most recently liked wallpapers. You can also find the most downloaded wallpapers from today to join in on what's trending. When you reach the download page, you'll get a large preview of the wallpaper with one download link. You can't download a specific size of the wallpaper, so you have to deal with whatever size they give you, but you don't have to create a user account and downloads start immediately. https://24wallpapers.com/wallpapers/Jedi https://24wallpapers.com/wallpapers/Samurai-jack https://24wallpapers.com/wallpapers/Targaryen-sigil https://24wallpapers.com/wallpapers/Hogwarts-crest https://24wallpapers.com/wallpapers/Twin-Peaks https://24wallpapers.com/wallpapers/Bob-minion https://24wallpapers.com/wallpapers/Clone-trooper https://24wallpapers.com/wallpapers/Deadpool
