Aperture is a project designed by Frédéric Eyl and Gunnar Green. They are 2 students on the University of the Arts in berlin.
Basically, it’s a giant reactive wall buil of hunderds of photosensitive diaphragms. Consisting of an iris diaphragm matrix, the facade’s surface with its apertures’ variable opening diameters is enriched by a dynamic translucency, that creates new imagery as well as a new channel for communication between inside and outside.
