"Natural Materials" is a free live wallpaper app offered by SHARP CORPORATION and can be accessed through their official smartphone app "My AQUOS". The app offers two types of backgrounds to choose from - one with rotating nuts and the other with dancing leaves.

The app is easy to use and offers a refreshing feel to your smartphone's home screen. Once you have selected the wallpaper, you can enjoy the soothing background and the natural movement of the elements. The app is perfect for those who like to customize their home screen and enjoy a natural aesthetic.

However, one downside is that the app is only available for Android users. Overall, "Natural Materials" is a great addition to SHARP CORPORATION's app offerings and is definitely worth trying out for those who appreciate a touch of nature in their daily lives.
