City Sleep Light makes a radical move by transforming a whole building into the sleep light of the city, akin to the sleep light of a computer. All the lights are pulsing together in an organic rhythm, turning the building into a living organism. Computed from the current global socio-economic activity of the city, the rhythm of pulsation differs each night and changes from one place to another. For the festival, City Sleep Light will be visible in each city, literally connecting inhabitants through multiple adaptations of the project on the facades.
