Six frames from "Conversation" a Slow-Scan TV work by Eduardo Kac realized at the Centro Cultural Três Rios, in São Paulo, on November 17, 1987. Slow-Scan TV allowed the transmission/reception of sequential still video images over regular phone lines. It took from eight to twelve seconds to form each image. Instead of considering each picture as a final form or the sequence of images as illusion of movement, Kac explored the live process of image formation.
