The image shown above is a snapshot of a new application they are working on. Practically the homebrew application under development will allow to insert the lock screen a sort of Live Tile able to provide information to the user, suchas RSS feeds, pictures, weather, etc.
The application name was not decided as yet, but have in mind to call it "lock widgets" or something like that. Another interesting feature that would implement this application is to change the lock screen wallpaper automatically according to the images that offers bing day after opening the app using the search button.
