Created by Ernest Edmonds in collaboration with Stroud Cornock, DATAPACK is a seminal example of an early interactive computer-based art system. It was shown in 1970 ar the Computer Graphics’70 conference held at Brunel University.

“DATAPACK was, as Cornock described it in 1973, “an example of a matrix that consists of participants, a display, a computer installation and a designated area around the Vickers Building next to the Tate Gallery in London”

DATAPACK was a networked system that allowed participants to have a “pseudo-English conversation” with the computer. The results of this conversation were then processed by the machine connected to drum plotter. This was able to identifying a volume space around the Millbank Tower and allocating it to the active participant.”
