SAM was the first moving sculpture which moved directly and recognisably in response to what was going on around it. It was exhibited at the ‘Cybernetic Serendipity’ exhibition which was held initially at the Institute of Contemporary Art in London in 1968 and later toured Canada and the US ending at the Exploratorium in San Fransisco.[1]
