Abstract: An entertainment or amusement structure includes a base support, frame structure, elongated walkway supported by the frame and a horizontally disposed cinema screen. A major portion of the walkway is positioned above the screen and enables viewers to see images projected onto the screen. The walkway may be an arcuate form and may be slightly movable to increase the feeling of realism for the viewers. The frame structure may be within an enclosure, an integral part of a building or a skeletal form. The amusement structure is particularly suited for viewing cinematic programs filmed by a wide angle or fish eye lens. A rear projection or front projection system can be used and the screen may be an elongated length of translucent film or material or a plurality of panels fitted in edge-to-edge relation and held by a support.

Abstract: An entertainment or amusement device or structure (10), having an elongate chamber (18) bounded along it length by at least three elongate, substantially planar walls (22, 24) with at least two adjacent ones of those walls (22, 24) having reflective surfaces. The device has an image generating means (30) by which a primary image can be formed across one end of the chamber (28) so as to result in secondary images being generated by reflection of the primary image by the reflective surfaces. Also, the structure (10) is adapted to enable viewer access (20) for simultaneous viewing of the primary image and the secondary images. In the case of a structure (10), the viewer access is enabled by a gallery (20) at the end of the chamber remote from the one end (28). Typically, the reflective surfaces (22, 24), and optionally also a screen (28) of the image generating means, are defined by reflective tiles so that the secondary images, and optionally the primary image, is perceived as comprised of pixels.

Abstract: An entertainment structure principally intended to comprise a cinematic auditorium. The structure has a horizontally disposed floor or decking support plate on which seating for members of an audience is arrangable and support means on which the support plate is rotatably mounted. Orientation varying means are operable to tilt the support plate, from the horizontal, in a required direction; while drive means are operable to rotate said support plate on said support means about an upwardly extending axis. The structure also includes a drive system operable to actuate said orientation varying means, and control means operable to control actuation of said drive means and said drive system for varying the angular disposition and tilt of said support plate with respect to said axis. In presentation of a cinematic programme, viewers perception of the action is enhanced by such rotation and tilting being synchronized and in concert with visual and aural action of the programme.

Abstract: Apparatus for producing a three-dimensional effect from a two dimensional image carrier having a focussed area containing principal subject matter and a defocussed area containing incidental subject matter. The apparatus includes a camera lens system, an optical device mounted within said lens system and a stereoscopic viewer. The optical device comprises a module which includes a pair of colored filter elements of different wavelength passbands, the filter elements being displaced laterally on opposite sides of an axis of said module, the module being arranged to cause an aberration to be formed on at least some of the incidental subject matter in the defocussed area but not affect the principal subject matter in the focussed area.
