Abstract: A free-standing collapsible panoramic theatre is described. When assembled, the theatre includes a multiplicity of vertical screens arranged in a polygonal arrangement that defines an internal viewing region. The viewing screens are supported by a multiplicity of towers which are located external to the polygonal arrangement with one tower located at each vertical corner of the polygonal arrangement. Each tower has a base, a support structure extending vertically from the base, a manually-operable alignment mechanism which permits the vertical orientation of the support structure to be adjusted, a pair of upper and lower screen support brackets mounted for telescopic movement on the support structure and releasably retaining the pair of adjacent viewing screens at the vertical corner associated with the tower, and a projector support housing for supporting a projector.
