Claim 8:
9. A system for emitting a composite of at least four substantially spatially overlapping and ongoing distinct private video streams, where a person views substantially only one of the distinct private video streams using a video filtering lens, comprising:
one or more projectors for emitting a composite stream comprising the at least four ongoing distinct private video streams, where the output composite stream is substantially spatially overlapping upon a reflecting surface, where the composite stream comprises an ongoing sequence of spatially composite video images, where a spatially composite video image comprises a multiplicity of emitted pixels that are filtered by the video filtering lens to reveal to the viewer substantially only one of the at least two distinct spatially filterable private video images each related to a different one of the distinct private video streams, where the pixels are filtered based upon the spatial characteristics of light being either of (a) limited to three distinct narrow bands forming an RGB color triplet, (b) being limited to substantially one distinct linear angle of polarization, or (c) comprising both (a) and (b), where in the case of (a) or (b), and optionally in the case of (c), each of the at least two distinct spatially filterable private video images forming at least one private video stream further comprise (d) two distinct temporally filterable alternating video streams such that in the case of (a), (b), or (c) the composite comprises at least four distinctly spatio or spatio-temporal filterable video streams, and
at least one video filtering lens through which a person looks in order to perceive substantially a single distinct private video stream, where the video filtering lens differentiates between the at least two distinct spatially filterable private video images and optionally differentiates between temporally distinct private video images.
