Scientists make 3D images move in air like 'Star Wars'
US-based physicists have created floating 3D images that viewers can see from any angle. Researchers said it's "not a hologram" as it gave an all-round view as shown in the 1977 Star Wars film where Princess Leia called for help. Millimetre-sized images were created with lasers guiding a particle in air while projecting colour onto it using 'volumetric display' technique.
