How to get a live wallpaper?
That would be cool 
From what I understand windows took out the ability to run gifs or swap pngs with an ini file as the desktop wallpaper so you can’t do it anymore without using third party software.
Sorry for the late reply, but this might be close to what you’re looking for - provided you don’t mind tinkering with it.
It is a live wallpaper, and it’s amazing. Many of them allow you to change certain element of the wallpapers - replacing them with what you want. I changed one to the Nightmare Before Christmas, and it looks great.
