The origins of this movement are attributed to American artist ALLAN KAPROW (1927-2006) who also championed the happening. Its roots lie in the Merzbau (1925), assemblages and kinetic lightshows of German poet and painter KURT SCHWITTERS (1887-1948).
The environment is the three-dimensional context in which content, sensory sensations, kinetic stimuli and imagination are synthesized in an effort to involve, and sometimes overpower, the spectator.
