The series “17352799” consists of four steel blocks, which have been cut along a line into several parts. The respective cut line results from my finger movement when unlocking my mobile phone and is therefore physical manifestation of my passcode. All of the cubes in the series represent the same code, but the sections are always different, since the individual movements, from which they origin – similar to a signature – differ slightly from each other. The intervention of the cut refers not only to the lock and key itself by the interlocking of the resulting parts, the resulting intrusion of the massive steel block also reveals the vulnerability of this system.
