Otto Piene discusses his projects with new media as well as the history and tradition of techological art. Topics range from archaic megalithic structures to large-scale, outdoor contemporary works articulated and enhanced by electronic forms of expression. Piene discusses his concept of ‘sky art’ and examines his attempts to expand the physical proportions of art and to communicate publicly with a large audience. Other issues raised include the beneficial effects of integrating art and science, the need to reevaluate and update art education and the importance of developing new forms of technological art that will improve communication and more effectively express human concerns.

Vibeke Sorensen describes her technical approach to computer stereographics and discusses in detail the actual genesis of several specific projects. She also discusses the history and future of spatial imaging, including its potential for challenging the centuries-old domination of twodimensional pictorial expression. Sorensen concludes her remarks on a cautionary note, stressing the need to place at least as much emphasis on the exploration of personal ideas and feelings as on the development of new hardware and computational processes. Robert Russett provides an introduction and background to Sorensen's life and work.
