Conversations is a live Slow-Scan Television (SSTV) work realized at the Centro Cultural Três Rios [Três Rios Cultural Center], in São Paulo, on November 17th, 1987. SSTV allowed the transmission and 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 is concerned with the live process of image formation.
