Just a couple days after releasing Face Swap, Microsoft Research is at it again with Face Mask. Where Face Swap used facial recognition to let you move mugs between bodies, this new app adds humorous features people's faces. Choose between 20 different masks, rotate or resize them, then make your friends look ridiculous. Face Mask can identify multiple faces in a snapshot and can randomize masks between them simply by shaking your phone. Pictures can be saved to the People Hub, as well as shared via Facebook, Twitter and Sina Weibo.
Like its sister app, Face Swap, Face Mask is free. You can get it here. Also, if you enjoy this app, check out Funny Faces too. Thanks for the tip, Shadi!
