Turning Soap Film Into a Projector Screen 37

Posted by timothy

An anonymous reader writes "3 graduate students from University of Tokyo, Carnegie Mellon University, and the University of Tsukuba have developed a colloidal display — a clear projector screen that can control its transparency. Normally soap film will allow light to pass through, but the colloidal display does not. It mixes colloid into the solution and uses ultra sonic speakers to vibrate the surface of the soap film to achieve this. They have created several prototypes, such as 3D planar screen, to show how this technology can be useful."

    The major problem with soap films, and one that I cannot see ever being fixed, is the total lack of compelling storyline. There is a reason why soaps have never made it out of daytime TV, and film adaptations would be a guaranteed flop.

    What film studio in their right mind would want to fund a soap film?
