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. "
