Simply place an iPad on top of the pyramid-shaped screen, which uses three special types on film, to create a display where the screen image appears to be floating in the middle of the pyramid. By reflecting onto the screen, the video contents using a multiscreen application, a 3D image appears when viewed with the naked eye from all angles, using the reflection angles of the filmed image. The filmed images also changes interactively in response to the sound picked up from the iPad microphone.
