This is a simple machine, which uses some rods embedded with LEDs that are spinning at a high rate to create seemingly 3D hologram videos in space. The concept of persistance of vision (POV) is very old and that's how a lot of still images stitched togather appear as video to our eyes.
The same concept has also been used to make fans that display holographic messages
