About this application

Cardboard Museum is an Android application for changing the device wallpaper at intervals using images from Danbooru. It is intended for users who want a rotating wallpaper source rather than selecting each background manually. The app focuses on wallpaper management and retrieval from that specific image service.

Because its stated platform is Android, it is not presented here as a desktop wallpaper tool or a general image browser. Its usefulness depends on whether Danbooru is an appropriate source for the user’s wallpaper preferences and whether periodic automatic changes fit the way the device is used. Cardboard Museum is published by ForgottenUmbrella and is distributed under the GPL-3.0-or-later license.
