4d pixel: if these walls could react
Daan Roosegaarde's 4d pixel is an interactive surface that reacts physically to stimulation by voice and music. The dynamic wall's surface is made of hundreds of physical "pixels" that activate in response to stimuli to display patterns or text. The concept is to explore the possibility of spaces that are responsive and adaptive to their inhabitants, as an interface controlled directly or indirectly via physical activity. 4d pixel is currently in exhibition at Berlage Institute in the Netherlands, and is being developed on a large scale as a public building facade.
