VIROSE is a non-profit organization dedicated to art and media technology based in Porto, Portugal. Normally is designated simply as an organization for the theory and practice of the old and the new media (Virose - art, theory, practice). It gathers artists, programmers, architects and others and runs a server with several areas, including an e-zine  and free hosting areas. Since the beginning of the project, in 1997, the main question was to understand digital arts in the broader sense of art. The problems of net.art, digital art or whatever are no so different, and even less opposed, to the ontological question that put together (and apart) art and technic. Is it possible to speak about a plural of the arts without thinking also its singular? And is it possible to sustain the singularity of each art without its plural?
