Get a great look for your iPhone or iPad by downloading a new iOS 7parallax wallpaper. Here's how to select a new iOS 7 parallax wallpaper, where to download a parallax wallpaper, and how to set a new iOS 7 parallax wallpaper on your iPhone or iPad. A key part of iOS 7’s new visual look is the Home screen parallax effect, which creates the illusion that your app icons are floating above the background image, as you tilt your iPhone or iPad. iOS 7 comes with a selection of wallpaper images that work well with the parallax effect, but if you’re after something different, there are plenty of places you can get more images from.
