The present invention discloses an improved concealable and a collapsible system for outdoor purposes for projecting holographic images depending on the ambient light, wind and other environment. This system comprises of projection screen (106) and medium for projection (104) hingedly attached along one of its length by hydraulic pumps (105), a plurality of sensors attached to the projection screen (106), a ultra-throw projector (103) and other surrounding structures (102) for image enhancement. The concealable stage not only provides protection from external forces but also does not obscure the natural scenic beauty. |
