From the Amazon.co.uk synopsis:
"Christiane Paul surveys the developments in digital art from its appearance in the early 1990s right up to the present day, and looks ahead to what the future may hold. Drawing a distinction between work that uses digital technology as a tool to produce traditional forms and work that uses it as a medium to create new types of art, she discusses all the key artists and works."
Digital art, relying on the spectator's interaction with the works of art, resemble non-games in several ways (not coincideltly, Toshio Iwai, creator of Elektroplankton, has one of his works cited).
