ABSTRACT:
A bubble-shaped display screen is adapted to fit over a "fish-eye" portal to a modular playground compartment, and may either replace or augment the transparent portal window. A projection device projects video images into the display screen. The display screen and projection device may be contained within an encapsulating enclosure which readily attaches to the modular playground compartment over an existing portal, allowing retro-fitting of existing playground structures. A beam-splitter and mirrors permit the projected video image to be viewed on either of two display screens mounted on either end of the enclosure encapsulating the projection device, permitting children within the playground structure and individuals outside the playground structure to view the same image.
