Ratchet Up has an interesting item on its site about new and unusual projection surfaces, including:
FogScreen, an invention that replaces a conventional screen with fog.
"The basic components of the [FogScreen] are a laminar, non-turbulent airflow, and a thin fog screen (or any particles) injected into and inside a laminar flow. Created this way, the fog screen is an internal part of the laminar airflow, and remains thin, crisp, and protected from turbulence.
"The FogScreen works very much like an ordinary screen in terms of projection properties. It can be used for both back- and front-projection"
I02 Technology's Heliodisplay -- an "interactive free-space display" or "floating touch screen" -- does away with the screen altogether, "[projecting] TV, streaming video and computer images into free space (i.e. mid-air).
"It's not a holograph. It's even possible to grab the free-floating image, or wrap your hand around it."
