(Phys.org) -- A team from three universities developed what they claim is the worlds thinnest screen from a bubble. They have figured out how to project images on soap film made of special properties and with a technique where images can run flat, textured, or even appear as if they were 3-D. They are using ultrasonic sound waves emitted from speakers to alter the surface. Also, they have found that by using a single projector, the texture of any image can be changed. An object such as a ball can be made to look smooth or rough. Their bubble is not the type of bubble waved away or popped by children at play.
