screenless displays

[Darren Dirt]

First came Fog Screen (via tiny water particles -- so you can walk through it)


Then Helio Display

Now: Displair, "the Air TOUCH System" (it uses a smaller steam-generator along with a projector and some infrared sensors, to allow for more control including "touch" interactivity).
