Ninja Shadow Warrior is a stand alone photo booth arcade game by Kaho Abe using the Kinect camera, Processing and a hacked closet light button built into a custom game cabinet. The game promotes face-to-face cooperative interaction through strategy, rather than rules, as multiple ninjas can fill out object silhouettes more accurately. The palace is under attack and the player must use ninja magic to hide, by “becoming” objects. The score and the photos are posted on tumblr and available to share on social networks.
