In the video below, see examples of University of Tokyo researchers using speakers to suspend objects in the air and then projection mapping to make them glow, a la Pixie Dust, as the team is calling it.
Explains Wired, “While acoustic levitation isn’t entirely new, the Japanese researchers have taken what they call the ‘digital controllability of non-digital objects’ to impressive new levels. They can tug a small screw to and fro, for instance, and let part of a floating grid of sand fall away until just a floating cross remains.Levitation is plenty cool in its own right. But the projected graphics steer the work toward some real world applications.’
