Amazing Lock Screen
This app was previously named Bing My Lockscreen but has now been renamed to Amazing Lock Screen.
I am very proud to announce my very first Windows 8 application: Amazing Lock Screen – which does pretty much what the title says it does. In short: Bing has the greatest images, and now you can use them for your lock screen!
Bing My Lockscreen allows you to select from the eight most recent 
Bing images and quickly select which of them to set as your lock screen.
In addition, Amazing Lock Screen allows you to automatically have your lock screen updated daily with the latest image from Bing—thus ensuring a constant supply of inspiring and interesting new content for you!
You can get the app from the store using the download link below!
Bing My Lockscreen makes use of icons created by the awesome (and free) Metro Studio 2.
