The live wallpaper from the Sony Xperia Z2 has leaked, which means you can give this a try on your Xperia phone right now. You will need to make sure your handset is rooted and that it runs at least Android 4.1 Jelly Bean. To install, download the apk here and move it to system/app. You will then need to set the correct permissions (RW-, R–, R–) and reboot your handset once completed.
You can then activate the new Xperia live wallpaper. Please note that the colour used cannot be set, the colour of the wallpaper will change as you swipe around your home screens. The colour changes from Purple > Pink > Red > Orange > Yellow > Green > Blue > Purple. Enjoy!
