Ciels variables (2011)

Ciels variables (variable skies) is a media installation that employs the matrix structure of the digital image to represent spatiotemporal phenomena. Using webcam archives as raw material, it displays a yearly sampling of the sky at different latitudes on Earth. From midnight to 11:59 PM, a part of the sky was analysed and translated to an image with the use of a slit-scan technique. The 365 images generated for each geographic point are looped on 7 synchronized LCD screens. The 14 channels soundtrack was created using a synthesis process wich converts the image's colors and brightness to sounds.
