This technology isn’t new, it’s been used at Disneyland’s Fantasmic show for well over a decade, but this is the first time I’ve seen it used for a temporary promotion.
To advertise the film ‘The Water Horse’, promoters are creating a hologram by projecting the Nessie image over a very fine mist being sprayed in the air. The effect is quite good. Something the producers of ‘Cloverfield 2′ should keep in mind.

That was pretty damned cool!
The next step towards the holographic suite on STNG…
I saw a similar water mist system on HGTV last year that you could project a TV image on. Maybe the next big thing will be something like this to replace the home theater…
