Institute of the Arab world, Paris, France. 2/2

@Cathie et Michel: Merci :)

@Aayawa: It's already in colour ;) It's juste de place which is made of steel and glass ; conbined to the clouds, and you got something light, like displayed.
By the way, using different points of vues, and/or a polarizer gives differents tons of colors to it, it's very strange in fact...

@colin: Thanks :)
