iOS 7 brings this cool little gimmick that allows you to set a panoramic wallpaper which moves in accordance with your own movements when you hold the iPhone / iPad in hand.
As detailed in the video above, all you need to do is access Settings > Brightness & Wallpaper > tap on Wallpaper > scroll down and choose Panoramas > pick a panoramic photo > and set that photo as your wallpaper.
As with regular wallpapers, you can set the image to display only on your Lock Screen, only on the Home Screen, or both.
When you move around, the phone’s motion sensors (accelerometer, gyroscope) work together to determine how the image in the background needs to move to follow your actions. It’s a neat addition to iOS, and one that many Apple fans will love to use with their own panoramic photos.
