If a signal is digitally transmitted it is represented as an information unit. Accordingly, all information contained in a computer can be represented by the units 0 and 1. In this context Digital Art circumscribes all those works of art that have been created digitally, usually by means of a computer. Therefor the terms Digital Art and Computer Art are often synonymously used.
Digital Art is a form of media art consisting of two variants. On the one hand, Digital Art is computer-made art, on the other hand it is a form of art that is explicitly dealing with the internet, using it as both source and forum, thus it is often regarded as Net Art.
The most important formal characteristic feature of Digital Art is its self-referential examination of the medium, which makes for a great part of the work's importance. Additionally, Net Art makes use of the internet as a means of communication and reflects the medium's effects on society. While Computer Art was forming as early as in the 1980s, the development of Net Art began in the 1990s.
Animated and thus moving characters are an important part of Digital Art, besides that, the observer is often invited to participate, as Digital Art can be opened up only in an interactive process. The interactive installation "The Legible City" (1988-91) by Jeffrey Shaw and Dirk Groeneveld is groundbreaking in this respect, as the visitor can only enter the virtual computer-programmed room after having pedaled a connected bicycle.
Important representatives of Digital Art are Agnes Hegedüs, Peter Weibel, Maciej Wisniewski, Dirk Paesmans and Joan Hermskerk.
