Most works of art stand before us uncoded and easily accessible to our senses and emotions. It is a peculiarty of media art that one needs an apparatus and sometimes even a code system in order for it to be accessible. By apparatus we refer – using Vilém Flusser's concept – to the tools and the knowledge concerning their use, by code we should understand special individual systems of notation. The preconditions of presenting and preserving a work of nw media art are firstly the apparatus and secondly the knowledge and functional presence of the code system. There are points of intersection between the different apparatuses: a reproduction is more often close to identical with the original than before the emergence of technical mediums. The disappearing elements of one apparatus can be replaced by a new apparatus. What are the new artistic possibilities for works made for the internet?
