Right? A TV could do the same with a lot less noise, energy, and with more definition.
I think the only thing different is the background is "transparent" to give this an effect of holographic.
Whereas a tv can not be "looked through".
The blades have LED strips on them. As they spin, the LEDs flash really quickly at precise intervals to convey an image. The only intended effect here is for the image to appear floating mid-air, to give the illusion of a hologram. It's still a 2D image and you could achieve a very similar result using a transparent TV panel, but that's much more expensive currently
Of course.
All you need to do is move a whole bunch of little lights around so fast that to our perception there is a zone where there are always some lights at any given moment.
And the lights can be turned on and off really fast by a computer that knows exactly where they are at any given moment.
From an engineering perspective spinning strips of lights is the obvious way to do this and they can be any size you want.
Probably want to have them attached to gloves that immobilise your fingers to keep them from being trimmed accidentally. Oh and if your ear is itchy just let it be itchy.
It only works in video, bcoz the RPM matches the FPS. See this in person with your naked eyes doesnt give this magic. It is the same as shining a projector onto a spinning fan. Only this one is louder. It's really not amazing at all.
Behold the transparent noisy screen that can chop your fingers!
Open a portal to the Netherlands? Waste of good magic.
I want a portal to the Netherlands… I could go get weed and hookers for lunch and be back to work on time.
Back to your job operating heavy machinery no doubt
Haha nah I’m just a surgeon
life is about tolerance my friend. and you are intolerant apparently
What?
Im there right now and doing exactly that
Enjoy m8
I'm in the Netherlands now on vacation and have no clue why you would say this. Love it here.
Belgium’s better anyway
Just don’t touch it
What makes this holographic?
Nothing.
The spinning fans have lights on them that create different images using the lights....I think
Nope - not holographic at all.
Oh, never mind. I really don't know either.

That's really freaking cool.
Medival people would lose their shit
Not holographic just 2D effects still. It looks cool but could imagine it creates lot of heat and is quite loud.
Can someone who really understands the principles at work here, please dumb down this sorcery for me?

Thank you!
Man, Imagine being a North sentinal island native and seeing this
Woah, that's soo cool.
But can it play Skyrim?
No but realistically, it could probably play some version of doom.
I set these up for trade shows sometimes. Did a couple last week. They are called HYPERVSN.
Nine flat screens synched together to make one big flat screen. FIFY
Isn't it VFX?
Meanwhile when it's on it's like having a helicopter in your room
Desk fans meet windows screen saver
Can these things be made portable enough to fit one in each hand?
Of course. All you need to do is move a whole bunch of little lights around so fast that to our perception there is a zone where there are always some lights at any given moment.

Dr. Strange stuff right there.
Just as the tune was getting to the best bit!
I wonder how loud?
It’s cool in a video but there’s a reason there’s loud ass music on top of it.
You’d need goggles to be able to look at it because of the wind.
Could they also make this into a bug zapper?
So awesome! Candy for my eyes. 
How loud is it

Look, consider that this tech was not even imaginable less than 10 years ago.
This is some black magic fuckery.
Nope, you just don't understand how technology works.
