'We were students looking to develop a network that would have a cultural impact - some way of organizing that would give us enough financial, hardware, and labor resources that we could begin to construct a platform for a public voice. Collective activity seemed (and still seems) to be the best option.' CAE 'Required reading for anyone concerned with disrupting authoritarian power in all its hideous forms.' Natalie Bookchin The third volume of essays in tactical media from the Critical Art Ensemble traces the developing topographies of digital intervention. Indicating that no cultural bunker is ever fully secure, the CAE show the possibilities of trespass, unleashing semiotic shocks that collectively could negate the rising intensity of authoritarian culture. Topics include contestational robotics, the financial advantages of anti-copyright, the mythology of terrorism on the net, recombinant theatre-as-resistance, and the possible role of children as tactical media participants.
