Some call it 3D, some call it holographic projection
The illusion is at its best when rotating objects are shown.
Typical scenario is that of a person appearing on stage, presenting, disapearing, re-appearing and so on. This time I had the luck that the scenario was somewhat different. An animated character (part of the identity of the brand) comes on stage, is the host of the show, asks questions & appears in different settings.
