Video: During a recent business trip to China, the folks at Big Screen Video, an Australian company that makes giant digital signage, found a brilliant little gadget that appears to replicate the 3D floating holograms Tony Stark uses in his laboratory.
What you’re actually seeing is a 3D animation being played back on a handheld fan that uses LED-covered blades to function as a display when the entire thing is spinning. That’s why you’re also seeing those rotating black lines slicing through the animation; the motion of the spinning blades doesn’t quite line up with the shutter of the camera recording this video. To the naked eye, this would be an even more convincing illusion, and without knowing the secret behind it, the hologram could make anyone wonder if someone has already secretly recreated Stark’s Iron Man armour as well.
