Almost everyone who looks at a cylindrical anamorphosis, reconstructed in a cylindrical mirror,* is struck by the impression of depth and 3-dimensionality in the reconstructed image. The effect is particularly evident if the subject is a photographic image. A further fact is that the cylindrical anamorphosis is extremely tolerant of being viewed with 2 eyes and from points rather far from the proper eye-point. These two facts which are connected are examined and explained with demonstrations. The result is a method of displaying motion pictures with a rather natural amount of depth without the use of special eyeglasses.

In addition a new form of stereoscope will be demonstrated based on the channel anamorphosis.
