ABSTRACT:
A display system, of the type used by exhibitors to attract attention or to create a desired background, is characterized by new and striking visual effects. The system receives projected images upon a mobile formed of a plurality of suspended panels free to move relative to one another in air currents. The panels, when aligned, form a surface, e.g., a rectangle having a format matching the image. Images are projected onto the moving panels of the mobile with a slide projector, film projector, or other image projection means. The projected image is separated into components by the moving panels and periodically the components coalesce partly or wholly when adjacent panels move into alignment. Changes in focus and distortions of linearity occur as panels rotate in relation to the projector's field of image. Striking and dramatic visual effects result. A still photograph may be converted into a moving, dynamic image, with devices that are durable and require little attention in use.
