The author discusses the relationship of interactive art to the structure of the computer, in particular commenting on artists' choices in using different kinds of systems, programs and interface devices. He discusses the problems inherent in the reduction of an artist's concept to a mathematical representation, a transformation that is necessary to allow a work to be implemented on a computer. Discussing the potential of the computer to allow a work to be able to change and grow over time through the extraction and storage of information, he looks for new, untouched directions for interactive art.
