An arrangement is provide for displaying a life-size live image of a person from a remote location in a three dimensional setting in a home location while providing the person in the remote location with a telepresence of the home location through the invention comprising: a video presentation system for displaying a person on a black background; a two way mirror for viewing both the setting and the superimposed video image of the person; a video camera or pair of cameras positioned in line with the eyes of the superimposed image of the person; and a network connection between the home location and the remote location. Stereoscopic views may be used in conjunction with the two way mirror and a retroreflective surface to display life-size autostereoscopic live images of a person from a remote location.
