Remember those suspended screens onboard spacecraft displaying vital info in sci-fi movies? We'', some guy has managed to invent them!!
Here's what the inventor sayz:
"The walk-thru fog screen is a novel and intriguing method for forming a superior quality physically penetrable dry fog display. It is a break-through technology, literally! The key features are that the screen is flat, enabling high-quality projections, and walk-thru is possible. The fog screen feels like nothing and does not make things wet. It creates a magical effect as if the imges are floating in thin air. This work has international patents pending.
Since announcing it publicly in Taejon, South Korea in Dec. 2001, the fog screen has gained an enthusiastic audience everywhere. The world premiere demonstration was in the Science Fair in Turku, Finland in October 2002. The prototype in the Science Fair was a success. It was covered in all the Finnish main TV news broadcasts, newspapers, etc. The fog screen has also been presented in New Scientist (UK), Wired (USA), Focus (D), and many other international magazines. The first permanent prototype installation has been running reliably in Vapriikki museum in Tampere, Finland since January 24th, 2003.
The basic components of the screen 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. When the screen is formed, images can be either rear- or front-projected onto it. The screen can be translucent (as in the images below) or fully opaque. Our current fog screen prototype already proves the operating principle with excellent results. "
