For those who read the Michel Houellebecq's latest novel, there is this intriguing quote "computer motherboards, which, when filmed without any scale indication, evoke odd futurists citadels"... which immediately made me think of this wall observed in a shop in Lisboa, Portugal.

In French: "les cartes mères d’ordinateur qui filmées, sans aucune indication d’échelle, évoquent d’étranges citadelles futuristes”
