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

The Single-Spin Hologram In Quantum Information Holography, everything begins with one thing: a single spin of light—its angle and phase—copied across Planck-scale qubits. The singularity is the derivative: the source of changing phase, the “slope” of reality. The horizon is the integral: the sum over those slopes, an interference image that becomes the world you see. Each horizon pixel is a Bloch sphere. At every Planck tick, these pixels freeze a time-crystal frame, and the next frame renders
