Kagemusha: Shadow Warrior is a new game I have been working on. It is a stand alone arcade game built with a screen and webcam. The goal is to fill out the shadow of an object as accurately as possible. Scores based on accuracy are kept on a leaderboard. The game structure of Shadow Warrior naturally supports face-to-face interaction, as more details can be filled out when more people are playing at once. This game will experiment with crowd sourcing content for the shadow object database.
