25 years ago, a firewall was a real, tangible wall used to prevent the spread of fire. Today, it is a virtual protection system in an electronic data system. In "Firewall," the exhibition, the term is used in a figurative and metaphorical sense to discuss the security problems associated with the increasing digitization of our world. This catalogue showcases the exhibition works of eight artists--six of whom created new works for "Firewall"--all of which reflect on the protective and unsettling factors associated with living in today's surveillance society. With innovative, cutting-edge, technology-inspired design, this catalogue thoroughly delves into the works of Jonas Dahlberg, Andreas Köpnick, Julie Mehretu, Aernout Mik, Julia Scher, Markus Vater, Magnus Wallin and Johannes Wohnseifer.
