Hologram

A photograph of an interference pattern which, when suitably illuminated, produces a three-dimensional image.

Typically three-dimensional, often animated, and sometimes accompanied by audio, a hologram is digital content formed by light that is projected on a transparent display or into open space. In augmented reality, viewers are typically able to interact with holograms; otherwise, holograms are generally passive/non-interactive content that can be displayed for an audience to view.
