Claim:
1. A system having an image production module adapted to: receive a first video stream and a second video stream; generate a first signal comprising images from the first video stream in a first polarity; a display module adapted to display the images on a screen simultaneously; and a visual aid to be worn by a viewer and allowing the viewer to view one of the displayed images and block the other image and to switch between the images, as required, using the same visual aid, the visual aid including a pair of polarized lenses, each lens being divided horizontally into top and bottom sections of perpendicular polarity with the top section of each lens being of the same polarity so that a displayed image of the first polarity can be viewed simultaneously through both eyes of the viewer through the respective top sections in one orientation and an image of the second polarity can be viewed through the bottom sections in each lens, in another orientation, wherein the different orientations are obtained by tilting the viewer's head up and down to look through the top sections of lenses or the bottom sections of lenses, wherein each lens has a thickness of about 0.4 mm, and wherein an angle of each lens is offset by about 10 degrees.
