"The "Line of the Horizon" art-science-technology project took place in November '86. The facsimile network (27 participant nodes) was spread over Mediterranean cities, but also extended beyond, to two boats (Atlantic, Indian oceans), and reached New York. This program provided us with: a) Observations related to the use of communications technology, and the proposed Together/Separate unit, useful for tackling interactivity -- a parameter not readily measurable, and b) The opportunity to check on proposed aesthetic criteria as they relate to communications in contemporary human and built environments. This geopolitical art network was activated from Thessaloniki, Greece, for a 6 - hours live exchange of respective horizon lines."
