Fan hologram type of 3D display technology

A Fan Hologram is a type of 3D display technology that uses a rapidly spinning fan and a series of LED lights to create a holographic illusion. The LED lights project an image or video onto the spinning blades of the fan, creating the appearance of a floating 3D object in mid-air. These displays are often used for advertising, promotional events, and artistic displays. They can be portable and easy to set up, making them a popular choice for various events and venues.
