Hologram

A hologram is a projected three-dimensional image that may also move and have sound. People often use holograms of themselves to communicate over long distances because it looks a lot cooler than just using a radio. In the Lukassi galaxy, exclusively light blue colored holograms have been in vogue for a long time and show no signs of letting up. Their technology formed the basis for HoloVision but not, despite its misleading name, the HoloNet.
