More and more artists chose to create art in public space, use it as a public stage, or try to actively change it. An "invisible performance", invisible, because it has not been publicly announced, may not physically change a place, however it may change the ideas of how to use public space in general.
Filipe Afonso's film Televisao is a (secret) filming of private spaces, where nothing more happens than the nightly projection of a television screen, and he questions the differences between public and private sphere. Laura Kissel records a specific situation. "Window Cleaning" in Shanghai shows two facade-cleaners, who become public performers with their high-up activities, but also possible unwanted witnesses of private scenes.
Kika Nicolela confronts people in places where usually no cameras are allowed, and where instead surveillance cameras always record.
Gabrielle de Bayon, Signe Theill and Nuno Escudeiro use urban spaces for their performances changing the concept of common uses of public space. Katze und Krieg actively engage with their surrounding. Here, it is not the authorities, interfering, but the crowd, not tolerating a slow-down in the public rush. And it is again, Vladimir Turner together with Vojtech Fröhlich and other artists, who hijack commercial billboards, turning them into other, more public use.
