ABSTRACT:
An optical device can produce a virtual image visible from a vantage point. The device has one or more lenses, a source for producing light, and an internally illuminable, non-transparent display object. The source can produce light in the display object in order to internally illuminate the display object and cause it to predominantly radiate internal light. The lens(es) can project a virtual image of the display object. In some instances two or more devices with matching display objects may be used to project one virtual image of the display objects. Each device is angled in order to increase the field of view of the virtual image.
