ART+COM‘s Timescope, re presents the past city-scapes of Berlin through a digitally augmented telescope. The “timescope” can be used for a wide range of purposes: it can be set up for use with tourist sites such as the Reichstag, the Brandenburg Gate or the Kaiser Wilhelm Memorial Church for example, giving visitors the chance to get a closer view of how these locations looked in the past. The “timescope” can also be used for large-scale building projects. In such cases it can be used not only to show how a building project has progressed, but also to show how a building will look in the future. Additionally, it can be used at geological interesting sites, enabling viewers to perceive natural history visually.
