a permanent light installation that aims to combine traditional surface decoration with modern display technologies which allow the building to communicate the changing weather cycles surrounding a gallery in the hours of darkness. 5 weather-proof window units emit light at night & allow sunlight to reflect during daytime. the units contain printed electroluminescence (EL) panels sandwiched between toughened glass & a mirror. a computer reads data from a dedicated weather station on site & uses this information to animate the printer EL pattern. see also public air quality indicator & blinkenlights.
