This would be filed under the category of useless apps that provide endless fun. Microsoft Research has released a new Windows Phone app – Face Swap – that allows you to swap your face with other people.
Face Swap provides an easy and quick way to swap people’s face using a photo taken with others. All you need to do it take a new photo or select an existing one in your library and then shake your phone once. Yes, that’s all you need for the Face Swap magic! You can save the swapped photos to your library, or share them on Facebook, Twitter, or SkyDrive.
You can try different combinations to see how your face looks on that gym-rat friend’s body. Maybe, just try your girlfriend’s face on your best friend’s body (No, not really). The app enables multiple faces detection and is available for free in the Windows Phone Marketplace.
