My Alien Buddy, Double Fine's free downloadable content for Sony's augmented reality game The Playroom, was released on Christmas Eve. It's an augmented reality mini-game where you play with deformable alien toys.
Double Fine previously developed Happy Action Theater and Kinect Party, which were both among the best reviewed games for the Kinect, so this is probably worth checking out if you own a PlayStation 4 and a PlayStation Camera. Plus, you can't beat the price.
