Adding another customization option Microsoft released beta version of Live Lock Screen. This application provide 6 new layouts to choose from, you can see a sample above. Each of these layouts also have a unique unlock animation too.
Those who have Windows 8.1 can download the application from here. It also allows you to change the background from your gallery or you may choose one from Bing every morning.
Earlier Microsoft said the application will need at least 1GB of RAM, while this application works fine on 512MB RAM devices too. Remember this application is on Beta (there can be other unknown issues, use it at your own risk) stage and have a slight delay to unlock.
