Within the location-dependent sound installation called "Project 4", the four seasons spring, summer, autumn and winter are pinned down as individual, partly invisible scenarios. Inside the confined system the visitor/customer may experience a superficial seasonal sentiment. Due to the pointed sound volumes inside a small radius, every single one of the four seasons is clearly audible in front of the sound's source. The visitor/customer abandons one season with increasing distance and enters another (season). Therefore I created an application that shows you some information about the project and how it was created.
