Abstract
An improved device for communication of graphic and/or pictorial information. In its simplest form, this device includes a graphic and/or pictorial information display element, a synthesizer element for electronic sound reproduction and a backing plate which couples to the display element and thereby defines a chamber for housing the synthesizer. The audible message produced by the synthesizer can be programmed for enhancement and/or complementary to the graphic and/or pictorial information depicted on the display element. This device can be used as a novelty item, jewelry-like adornments, enhanced security identification badges and various instructional and/or message oriented media.
