While we’re still a long way off from the Star Wars telepresence holographic displays, this build over on the Projects site is the closest we’ve seen yet. Even better, it can be built in a garage for not much money.
Inside the Hoverlay are a few fans and a pair of ultrasonic atomizers that turn water into an extremely fine mist. The fans pull this vapor up through the base of the display and through simple drinking straws to create a laminar sheet of water vapor. Put a projector behind this thin sheet of vapor, and you have a display, seemingly floating in mid-air.
The base of the display can be scaled up, simply by putting several units together in a line. It’s still just a prototype – future versions will improve the stability and reduce the thickness of the fog layer – but it’s still a very cool build for a custom holographic display.
BTW, yes, we know this isn’t a hologram. You’re still welcome to point out the fact that language changes in the comments.

I Always thought the starwars displays were extremely bad quality. Ihis image seems too stable… make it worse :P
And i thought that they were 3D, not only 2D… However it still looks cool.
This reminds me of Io2 technology. They make displays like this.
“so if you wanted a 30 cm tall female dancer dancing in your garage, thats probably not the easiest way to get that”
What fun would the easiest way be :D
Hire a midget, of course!
Perfect use for an animated gif as a teaser.
No it’s not. It’s never a good time for an animated gif. They are really disorienting and disturbing. Does anyone know a good way to block them.
Most browsers have a setting to disable animated gifs, or to play them only once. And many browsers halt animation when the escape key is pressed although firefox had to remove that hotkey due to a conflict, but there is addon to make shift-escape do it called ‘superstop’
Looks more like the technology used for the Professor in Seaquest DSV
I think that used condensing moisture from the air using dry-ice above the image to generate the ‘mist cloud’ but essentially, yes, it was a “project onto mist to create eerie floating person.
Anybody every tried using corrugated plastic (old election signs) instead of straws? It’s easy to find for free, comes in many different sizes, and is super easy to work with. Would the fact that the chambers are square negate from creating a laminar flow?
In theory, yes, a bit. I think it would work pretty well in practice though.
I tested 3d printed square chambers and they do work, though you might want to get some with a very small wall thickness since layering them together actually gives you double walls.
Quick! Edit out the use of “holographic display” before we get a hundred comments saying it isn’t holographic!
Wasn’t a company already selling these? “Heliodisplay” or something.
Sweet to see one made at home tho, mayor respect!
Nice job. Disney does this in their parks. But usually the fog drops down …
Please disregard the report comment flag. Nothing to see here, move along, move along.
(Can HAD fix thatso that it toggles instead of just sets?)
It’s really not much of a problem. Stuff is rarely reported ( THANK YOU if you do, btw ), and it only kicks the post into moderation after a few reports. If too many people do that, I review and kick back all the reasonable ones.
They have this exact thing running in the foyer of petronas towers in Kuala Lumpur, Malaysia only with a lifesize video presenter giving the welcome talk. Saw it a few years ago and though it was a nice touch.

Thanks for the article :) make sure to check out the latest build at http://iamnotachoice.com/hoverlay-2/
Please. This is NOT holographic. Merely flat projection on semi-transparent screen.
FOUND ONE! Found one right here!
depends on your projector. a regular off-the-shelf light field projector will do :)
It’s a 2D projection onto a water vapor screen, been done for years. Hell we had one in a very bad SCI-FI TV show from over 15 years ago SeaQuest DSV had one.
It only looks good from the angle they are filming from under the ideal lighting conditions.
Not my definition of “holographic”.
I hope your not saying SeaQuest was the bad show. SeaQuest was awesome.
(Well, save for the last season…)
Related although details are lacking:
Yet another clone of the original FogScreen. Down to the honeycomb. Someone already mentioned the late Io2, which was a similar copy.
Hypothicaly, could a design like this be used for a real volumetric 3D display?
If you had light being projected from a few angles at low intensity so it only adds up to a decent amount at the correct voxel position? Sort of like they use for medical ultrasound based surgery.
Just a simple housekeeping question, doesn’t it get quite wet? Is there a collection to recirculate the water or what?
target group are mostly turkish baths and tropical greenhouses :)
tweet me obi wan kenobi you’re my only hope…
Have you considered putting a little bit of milk with the water to make it a litter bit less transparent? This is a trick that Hollywood use to make rain look better on camera because it shows up better. I can’t wait to see the next vertion of this.
Technically, I really like this suggestion. But I’d be a bit worried that it turns the screen into a yoghurt factory. Maybe fog fluid works better. I recently released the Hoverlay II as open source, find it on http://iamnotachoice.com/hoverlay-2/
