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. Built from double-wall stainless steel and made to order, holding 20 ounces with a snap-on lid, a standard-cup-holder fit, and wraparound artwork. Your commute carrying original art instead of another branded tumbler.
