German artist Carsten Nicola designed Unidisplay, an audiovisual installation that uses screens and mirrors to create projections in real time at HangarBicocca in Milan. The piece is 40-meters long and makes sound perceptible on an optical level using variations of black and white and an array of acoustics. It visually interprets time and allows visitors to watch and interact as they please.
