Another Vapor Projector at Nextfest with Gesture Control Video

In addition to the fogscreen display overhead as you entered Nextfest there was another water vapor-based projection system.  Heliodisplay from IOtechnology also projects moving images onto a stream of vapor.  They also have an interactive gesture controled version.  Generates the same ideas to me for a gesture control surgical system.  Here my video of me messing with the images.  You can see the mirror projector in the back.
