 Defining virtual art broadly as art that allows us, through an interface with technology, to immerse ourselves in computer art and interact with it, Popper identifies an aesthetic-technological logic of creation that allows artistic expression through integration with technology.After describing artistic forerunners of virtual art from 1918 to 1983 - including art that used light, movement, and electronics - Popper looks at contemporary new media art forms and artists.He surveys works that are digital based but materialized, multimedia offline works, interactive digital installations, and multimedia online works (net art) by many artists.
