The Brenkert Brenograph Jr. was a projector used in atmospheric theatres to project moving clouds over ceilings painted blue. The effect created the illusion that theatre patrons were outdoors. The device was used primarily in theatre designs of John Eberson. The machine was manufactured by the Brenkert Light Projection Company of Detroit. The company sold the projector for $225 in the 1920s. The projector was small enough to be hidden in the theatre architectural design so that the illusion of floating clouds would be maintained.
