Key to his conceptual framework was the recognition of the changing character of natural and human-made environments and the consideration of such environments as a matrix of events in a four-dimensional time-space continuum. His fragmented and largely neglected theoretical and artistic sketches provided an iridescent contribution to the 1960s emerging discourse on Environmental Design. Boutourline’s conceptual approach reverberated central ideas of Whitehead's process philosophy, Wiener’s Cybernetics, Bertalanffy’s General Systems Theory, and McLuhan’s media theory. It emerged out of his ground-breaking 1962 research on audience behaviour in public spaces and took inspiration from his professional practice and collaboration in artistic projects informed by Schlemmer and Moholy-Nagy’s concepts of modernist theatre, Alwin Nikolais late-modernist abstract dance performances, and the 1960s countercultural avant-gardist experiments with media technology and human-machine communication in artistic practice. However, despite Boutourline’s acquaintance to key figures in the countercultural discourse on technological media, artistic practice, and the academic field of Environmental Psychology, there is hardly any reference to Boutourline in the critical discourse concerned with the development of art and design in the 1960s. This paper re-introduces Boutourline’s signal oriented conceptual framework and technological devices within the context of the 1960s countercultural avant-gardist experiments with human-machine communication. It further discusses links between his theoretical and artistic approaches and the emerging conceptual framework of environmental design.
