In screen-based experiences, the screen itself can become the physical device used for interaction. The "move-ability" of the screen affords interactivity between the screen artifact and the viewer and between the virtual and physical spaces. As a movable screen interface, we have created the spinning screen, a two-sided monitor on a revolving base. This interface invites user interaction through the action of spinning the screen to manipulate media content. By allowing viewers to grasp the interplay between visibility and invisibility, the spinning screen can enrich user experiences of virtual imagery through direct tangible interaction in both playful and practical contexts. We describe an art piece and an application for 3D visualization and modeling. Categories and Subject Descriptors H.5.2 [Information Interfaces and Presentation]: User Interfaces
