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. Constructed from woven polyester with a soft microfiber lining and a sturdy zipper, made to order for 13 and 15 inch laptops. Everyday protection carrying an independent artist's work, not another plain black sleeve.
