We describe a demonstration of four novel interaction techniques for a cubic head-coupled 3D display. The interactions illustrated include: viewing a static scene, navigating through a large landscape, playing with colliding objects inside a box, and stylus-based manipulation of objects. Users experience new interaction techniques for 3D scene manipulation in a cubic display.
