Network Time by Spiros Hadjidjanos.
The installation Network Time consists of several Wi-Fi routers arranged in the gallery space providing free Internet access to visitors. The LED that reflects the data-traffic of each router is extended along a fiber optic cable magnifying its flicker. Although the devices look only physically modified, the artist has altered the operating system of each router, to manipulate the fluctuation of the fiber optics. The installation is a network architecture installed in a physical setting, framing information as situated, temporal and contextual, constructing a permeable interactive and extended space.
