Wallpaper Engine
Wallpaper Engine is an application for Windows with a companion app on Android which allows users to use and create animated and interactive wallpapers, similar to the defunct Windows DreamScene. Wallpapers are shared through the Steam Workshop functionality as user-created downloadable content. It features its own rendering engine and provides a wallpaper editor, allowing for the creation of 2D and 3D wallpapers, including a particle system editor and a fork of JavaScript called SceneScript for additional wallpaper logic. It also supports using video files, audio files, web-pages and some 3D applications as wallpapers.
