3D Hologram Display Diameter 42cm, 100V The fan spins, and the image appears to float. I used to do this for work, but my main job has become busy, and I haven't had time to create images lately. The photos are of my home display, but I have a lot of new, unused ones in stock, so I'm clearing them out. Are you interested in using this for a store sign, for an advertising company, or to start a business with it? I've also included photos of it in use in a room. Please comment if you want multiple units. Cannot be used where it will get rained on!
