From the press release:
At the invitation of NAiM/Bureau Europa, artist Paul Devens has realized an installation in the upper hall with a total floor area of 800 m2. ‘Panels’ attempts to provide the visitor with an intensified architectonic experience. The installation consists of acoustic panels that follow the contours of the roof vaulting, largely obstructing the view of the shell roof. The panels overlap and slide past one another, so that ever-changing patterns arise. With the assistance of loudspeakers, microphones and a computer, the so-called ‘Larson effect’ (feedback) is generated and the space is transformed into a instrument, so that the experience of the Arched Hall consistently alters both acoustically and visually.
