The (Dis)appearance of Everything is an interactive installation that explores the convergence of physical material and light by rearticulating light as sound through Spectro-Sonic refrequencing. The installation’s architecture questions the limits of perception and activates the border area of natural phenomena and digital systems. Natural and artificial light merges inside five cast resin elements that appear to subtly shift in color and luminosity depending on the viewer’s position within the space. Two sensors, calibrated to measure both purple and daylight frequencies, drive a tone generator which converts the frequencies of light into frequencies of sound, making light audible. The sensors also register the presence of the viewer moving through the space, which additionally modulates the sound. In this set-up, virtual and physical information is processed both by the viewer and the work, further blurring the boundary between phenomenological and virtual events.
