We made an implementation of Jenga where the player can view the scene through a head mounted display and interact with a tracked pen. As an addition to the classical Jenga there are some very bad birds. They want to destroy the tower and the player has to defend it by kicking them away with the pen. I have developed Jenga together with Christian Fischl and we made the second place within the laboratory "Virtual and Augmented Reality" 2009 at the Vienna University of Technology. We used the "Studierstube" Framework and NVIDIA PhysX for this project.
