The apparatus comprises display means comprising a projector (11) and a back projection screen (13) for displaying pre-recorded visual images and associated text and a central processor (14) for controlling the display means together with a manually operable remote control (15) to enable a user to interactively control the images and text displayed. The apparatus may be used within a shop window to provide an image, typically 1.5 - 2.5 m wide x 1.5 - 2.0 m high, visible to potential customers outside the shop both during daylight and at night. |
