I've found these gems via iconeye.com and here is their words:
Icon is just back from Lisbon, where we attended the design biennial Experimenta.
Someone - a rogue architecture student? - has lined the bottom of a wall with the kind of buildings you might find in icon. The selection indicates that this particular graffer both knows his onions and has good taste: Peter Zumthor's chapel in Mechernich, SANAA's school in Essen, OMA's Casa da Musica and one building that looks suspiciously like Valerio Olgiati's Yellow House, but we may be wrong.
There are also classics, such as Jørn Utzon's Sydney Opera House and a collectionof Oscar Niemeyer's Brasilia buildings. We assume the upper panel of aboy playing Space Invaders and a girl blowing bubbles is by the same artist but the connection isn't obvious.
