Croon a tune, croak like a frog, hum, hoot, or holler—you don’t need to be Pavarotti to create dazzling shapes and patterns with the power of your voice. By humming, singing, or talking into the Vocal Visualizer, you’ll be able to see sound as vibration (or pressure waves) and experience cool laser-light patterns that are reflected on a wall or other surface. It’s a fun and slightly psychedelic introduction to concepts such as Lissajous patterns and resonant vibration modes. A Pink Floyd soundtrack is entirely optional.
