Cardboard Museum — Open Source Launcher App

A Muzei 3.0 plugin for the (potentially NSFW) Danbooru imageboard, which sets the wallpaper to an (anime/manga-style) image matching the given tags. Supports authentication to bypass account restrictions e.g. the default limit of a maximum of two tags. Additionally, the app tries to avoid NSFW images by default (although this is configurable), and there is the ability to preview potential matching images to be aware of what the wallpaper will be like. Code of the Danbooru Image Board can be found at Github.
