A video of an "electric fan" that can produce 3D images has wowed netizens around the world on the social media. The electric fan is actually a holographic 3D screen invented by a Chinese company in Nanjing, capital of east China's Jiangsu Province. The company's CEO and head of research and development, Zhou Quan, is a recent graduate of Southeast University in Nanjing. The smart holographic 3D screen has four LED bars that make it look like a fan. As the bars rotate, they produce 3D images whi

These fans spin rapidly to create 3D graphics that "float" in the air. These LED fan displays can create 3D holograms as you wish. They can all be controlled via WiFi in the accompanying app, where you can upload projected content as well. They were developed by Chinese company Enoptech, which specializes in multimedia display products and offers on-demand services for both leisure and business purposes. | GIGadgets
