VR/Urban is a collective of public media inverntionistas founded in 2008 and since then more or less working together to create public media realtime installations.
The aim of all projects is to reclaim urban screen for the public. In tradition of situative art and graffiti culture, VR/Urban augments existing city structures with digital and interactive media-art. The collective strongly believes in embodiement, accessibility and the tangibilty of information, so that each installation has a very performative and challenging character.
The core persons behind the VR/Urban group is the media computer scien-/arttist patrick tobias fischer, the designer and design researcher christian zöllner, software developer thilo hoffmann and design presearch master sebastian piatza. The team members are fluid elements of partners and friends in the fields of art, music, science, electronics, coding and architecture.
