Google is giving Pixel phone owners more case choices.

The company has released two new "Live" cases for the Pixel and Pixel XL. These types of cases rely on an NFC connection to change your wallpaper daily. The first new Live case is a Google Earth-themed one that rotates different landscapes from Google Earth across your screen. There's also a shortcut button you can press to learn more about the location you're seeing that day.

The second case is a Google Trends-themed case that surfaces trending search topics as your wallpaper. The topics depend on your location, and if you tap on one, you will see a new one appear. To learn more about the topic, press the shortcut button. The idea is you'll get to see what’s trending on Google, along with a visual representation of the trend's popularity in the last 24 hours.
