.. or is that just my tiny mind... ?

University of Tokyo and colleagues have created the world's thinnest
screen from a soap bubble that can display vivid images that are either
flat, textured or 3D.


Compared to conventional screens that are opaque, a
soap film varies in transparency and reflectance. The team was able to
control these properties by using ultrasonic sound waves emitted from
speakers to alter the surface.
