BZZZ! the sound of electricity is a sound sculpture by Cécile Babiole, exhibited at Plateforme-Paris in June 2012:
By reinventing an obsolete low-tech sound wave generator in this all-digital age, “Bzzz !” serves as a commentary on the history of technology and a tribute to unprocessed, unsampled analog sound : in a word, the raw sound of electricity.
The installation consists of 6 micro-controlers, 6 resistors scales, 12 small PA et 24 small loudspeakers. I love it.
