The occupants have left and have turned out the lights. Empty of words and images, the premises are the backdrop to a central shell, a complex structure with opaque functions. Drowned in semi-darkness, theses architectures do not betray their constitutive ostentation. Curves, straight and diagonales lines give a show, admiring their reflection on the walls. One leitmotiv appears : the geometrical abstration of quietly aligned multicolored matchsticks. The color bars, point zero of television time, spreads its rainbow over silent set.
