During the Apple keynote yesterday we saw a lot of interesting and exciting new things with iOS 7, many of which have been available on Android for some time, but we won't get into that now. The most impressive new feature and UI aspect (for me) was this "liveliness" 3D wallpaper doing the parallax effect. Showing the background image move as you tilt the device. Thanks to an eagle-eyed reader we've learned this is nothing new for Android. Check out our hands-on below of what surely is my favorite new app.
