a physical data sculpture representing the movement & communication made with a cell phone in the timespan of 1 week. the aim of the project is to draw attention to the German telecommunications data retention act & the breach of privacy it constitutes. the law requires the telecommunications providers to store the connection data of all customers for 6 months & to make it available to law enforcement agencies upon request. the density of the cell sites reflects the speed & frequency of a person's movement within the city. the more often a place is visited, the more cell sites were added to the map.
