As the viewer traverses Hetrophony they are immersed in a continually evolving planar space. Ripples track their movement, radiate and gently perturb the surface of the video image and sound space. Two pentatonic motifs loop and subtly transform in response to the viewer's explorations, interweaving and forming intricate and dynamic aural structures. The installation is recreated from one moment to the next, it's structures resonating within the Mediaeval architecture, the involvement of the viewer fundamental to its realisation. Its sparse, contemplative nature allows space for interaction and facilitates a active participation by the viewer. In this way it transcends the notion of computer as 'insertion box' and explores a more fluid mode of interaction.
