Loop is a space-time installation, tailor made for the main staircase at the Musée d’art et d’histoire in Geneva. It is part of the kinematope series, a set of site-specific works focused on the perceptual transformation of the environment through time based structures, materialized with ephemeral mediums such as light and sound. It is made out of sound from a repeated element already present in the architecture. There is a subtle shift of material, physically revealing the scope of the work. The acceleration of gravity is taken into account, bearing in mind the vertical arrangement. The sound structure repeats itself in a circular circulation, a loop within a loop.
