A waveform visualization merges nature and sound, with silhouettes of evergreen trees and flying birds rendered in shades of blue and gray against a black background, bisected horizontally by a rippling audio wave. The composition transforms acoustic data into a landscape, collapsing the boundary between what we hear and what we see in a meditative study of natural rhythms. Printed on smooth white card stock and made to order, artwork on the front, blank inside, envelopes included in every set. A handwritten note that arrives as an independent artist's work.
