Abstract: A viewing system for integrating images from an electronic display device with a three-dimensional display environment. A viewing device with a display housing has a viewing aperture into the inner volume thereof, and a reception structure receives and supports the electronic display device with the display surface thereof facing toward the inner volume of the display housing. A display insert or display slides establishing a three-dimensional environment are disposed at a display location within the display housing to be viewed through the viewing aperture. A two-way anterior mirror is disposed anterior to the display location and a posterior mirror is disposed posterior to the display location, each mirror disposed at an angle operative to reflect images emitted by the display surface of the electronic display device toward and through the viewing aperture to be viewed in integration with the three-dimensional display environment established by the display insert or display slides.
