As an integral component of contemporary culture, technology creates a potential for the development of dynamic spaces. These spaces have an ability to interact and communicate with users. To approach this idea, we proposed interactive wallpaper which responses to human activity. Wallpaper with a "transactive intelligence" (Ludovce, 2001) which can transform both the user and itself. The implication of such scheme can be wallpaper in spaces that lack sense of interaction and consequently create a dull environment. The best example of such space is a waiting room in a hospital.
