Ever wanted a screen floating in air? Two scientists, Ismo Rakkolainen and Karri Palovuori, both from Tampere University of Technology, Finland have come up with an idea. It is called the Walk-thru Fog Screen. The fog screen, consisting of 'fog' that is blown down from top, and the protective laminar airflow creates a thin and crisp surface, pretty undisturbed by the air in the rest of the room, making it ideal for projector usage, says Slashdot.

People can walk right through this screen of fog. Their next idea is to use the fog as a touch-screen, making it even more accessible."

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.
