Using video projectors and technology, it is possible to literally "cover" a solid image that is skillfully calibrated so that they do not undergo deformation and allow visualization of content without abnormal distortion as if projecting on a flat surface.
Fantasy may be the only limit in this case because it is practically possible to project images and videos on any surface, from classic buildings to more complex cars or perhaps make "live" products in a showcase.
With sophisticated video projector equipments we can stream multimedia content on huge, complex surfaces, creating playlists for both a show and advertising, there is no limit to the size of a video mapping.
