With iOS 7 Apple has introduced a cool new 3D parallax wallpaper effect ( see it in action in the pic above ). Although this isn’t nothing more than eye-candy that will decrease your battery life ( you can disable it by toggling on the “Reduce Motion” option in the Accessibility menu ), it still looks cool for about 5 seconds and you should have some fun with it. If you’re looking for parallax wallpapers, there’s a tumblr site that you can check out. Enjoy!
