Carl Fernbach-Flarsheim - Boolean Image/Conceptual Typewriter. From the exhibition Software in NYC, 1970. According to the under-age programmers of this piece, The R.E.S.I.S.T.O.R.S:
The exhibit was an anti-climax. The show opened in the summer, when it was rather hot, and the heat from all the computers made it even hotter. To keep the IDIIOM from overheating, they stuck a block of dry ice underneath which worked OK, but when the company saw what was happening to their computer, they took it home.
