This paper discusses the construction of the sunstance projection display and the interaction with it. This display system is composed of an object in the free shape, a video projector, and the sensor to measure the object's position/posture and the user's eye. The user can perceive the projected virtual object in three dimension that locates inside the screen object, since the eye-motion parallax and object-motion parallax gives the 3D cues to the user.
