The field of holographics - the study and creation of the three-dimensional photonic images called holograms - is a old as galactic civilization itself. Some holographers are inventors, others simply technicians, and a rare few are true artists of the form.
Public holographic kiosks are commonly used in galactic culture to make general announcements to the populace, to advertise goods and services, or to honor significant individuals with a "holo-statue." The basic technology is not difficult to operate or find in most marketplaces, though they can be found in a wide variety of sizes. Thee size of the kiosk generally corresponds to the size of the holograms they project - and some even come in handheld sizes.
