Photo Book 3D Live Wallpaper is an Android application developed by Zbigniew Ross under the Personalization category. It is a live wallpaper that displays randomly selected images from the phone's memory on the pages of an animated 3D book. The app allows users to select folders from which pictures are displayed and their quality.

It is worth noting that the app comes with a sponsored caller ID service that will add a few permission requests to provide the service. By using it, the developer receives a few cents to help keep developing more apps. However, users can delete the app or disable the feature in the app settings if they do not wish to use the service. Overall, Photo Book 3D Live Wallpaper is a great choice for those who have a lot of photos on their phone and want to showcase them in a unique way.
