New Tendencies refers to a neo-avant-garde movement at the time of the Cold War. It included groups that emphasised the collective and rejected the idea of an artistic genius. These include ZERO, GRAV, gruppo N, gruppo T, groep Nul, Dviženije and Gutai. They are associated with concrete art, kinetic art, op art and computer art. They see the involvement and activation of the audience in interactive environments as central tasks. It is an art that presents experiments in perception that are as objectifiable as possible and free of subjective expression. Both theories of perception and varieties of information aesthetics form the theoretical framework.
