In fact, this is a two-dimensional video image projected on a curtain of water vapor produced by an ultrasonic humidifier hacked onto a laminar flow nozzle made out of a bunch of drinking straws.  Not strictly a hologram, but still a very cool thingum.  It’s the work of Chris Weisbart, aka YouTuber ChristopherTalosian, and comes to us via Mike Senese, who provides this description:

Based on the concept behind commercial units, but using everyday items (drinking straws, scrap PVC pipe, a kid’s humidifier from the thrift store, some scrap computer fans), he rigged up a device that creates a thin, even sheet of vapor mist. Almost translucent, but able to catch the light projected onto it from a rear-facing projector — which gives an eerie, floating hologram effect…

A similar technique uses a piece of thin muslin as a screen, as for instance in this haunt-prop “Shining” twins illusion.  [Thanks, Mike!]

    Anyone else reminded of the fog screens used in SeaQuest DSV?

      Yep, sadly that might have been the best part of the show, as much as I like Roy Scheider.

    What would it look like if the fog wasn’t ‘laminar-ed’?  That is, can’t one project a solenoid (or flat) image onto yer basic foggy cloud?

    that’s pretty slick.  Hope we see an instructable out of this one soon!

    Assuming the resolution could be improved by using a cleaner sheet of vapour, if you connected that to a head tracking system, for one person at least it would appear semi-3D… 2.5D? :P

    Try hooking up the mechanism with two cameras that perceive the light of the person and sends a signal to two separate projectors, thus enabling the device with communicative properties.
