Aperture is a facade installation which functions as an interactive display. The display is created using iris diaphragms which together create an interactive matrix. Iris diaphragms are apertures with a variable opening diameter. The single apertures in the grid react to varying intensities of incoming light by altering their diameters correspondingly. This feature makes passers-by able to influence the opening diameter of the iris diaphragms by their movement in front of the facade, thus creating a display capable of depicting the people moving by, while at the same time being a new channel for communication between the inside and outside of a building.

Aperture is created by Frederic Eyl and Gunnar Green from the University of the Arts Berlin.
