An improved three dimensional display such as a Holiday decoration having collapsible constructions having a shape memory internal frame. In one embodied form, the unique display includes a collapsible internal frame formed, in part, from metal wire imparted with suitable memory characteristics. Such metals are referred to as“shape memory alloys”(SMAs) because much metals“remember”their original shapes. Accordingly, the present invention uses a deformable internal metal frame supporting an outer sheath formed from suitable materials such as fabric, or plastic film for the skin of the inventive three dimensional displays.
