Large holographic projector- a real use case 

+Saurav Chakraborty (Brainergizer) This is not holographic projection. This is simple projection on a transparent or semi-transparent screen (something which helps reflect light which helps us to see the image). True holographic projection is supposed to project images in thin air.

Where can you find a place that knows how to project images into thin air? Or at least a video about it?

Cosmic kitty .... please tell me you dont actualy think that someone has learned how to break/bend light physics and is just hording the tech somewhere when they could be filthy rich from the sale of this tech to the market. humanity is striving for "thin air holograms" as a side project. all of our current Solutions have a physical density mass weight and/or volume. The Smokescreen thing is cool but it doesn't have low Distortion and clarity is lacking as it can be interfered with by air currents. Current laser tech needs to take Leaps and Bounds to do anything of the futuristic 4d Holograms

@@Ishiku__aka_xchoibitschibihil Everyone always thinks things not accomplished are impossible to create or have so small chance of succes they just throw the idea away. This is bad. I actually think true holographic projector might exist somewhere in a lab. Only it might have flaws they want to put right first. It could also be too expensive and complicated to manufacture it.

@@relly8977 Kind of like Alchemy

With some hella powerful projectors I think you could but you'd need good contitions and not a plane, more like a crane with a long horizontal thing at the tip that water fall from. May work better with white water and I just got you joke so yeah... woooshed

Fog machine

It's probably not smoke, but rather mist from an ultrasonic humidifier.

noooooooooooo its all a smoke screeeeeeeennnnnnnnnnnnnnnnnnnnnn

noooooooooooo its all a smoke scrennnnnnnnnnnnnnnnnnnnnn

Any projector. just focus it on your smoke screen.

+Brainergiser (Brainergizer) It's beautiful! Thank you for sharing. :)

Oh, thank you for the prompt response. Do you know what the restaurant name is by chance? I'd like to know if they use a fog machine or water vapor.

A hologram is a 3 dimensional image. All of these examples are two dimensional ie: not holograms. They are just projected images.
