As detailed in the above video and a paper published Friday in Nature Communications, the researchers were able to manipulate objects with such precision that they could spell out words on the surface. To make this happen, they carefully constructed melodies where the frequency of the notes would cause the objects to move in a predictable manner along nodal lines specific to that frequency.
