Each generation coming of age looks for a contemporary foothold for the gradually evolving identity. For my generation – detached from sociological cohort of generation Y –Atari, Rubik cube or Pet Shop Boys are anachronistic values of time. Today’s free Internet space, for years a carrier of anarchist and counterculture values, for us – “Children of the Web” – is the area of everyday life activity. Global and flexible virtual realis, penetrating into our reality with an RGB glow, was filled with noble omni-creativity, developing a self-updating definition of today’s culture that we are keen to participate in. Technological developments left a strong mark also in the field of art, the symbolic form of which has become the phenomenon of virtual art galleries – defined as post-galleries – the subject of my research. In my dissertation I address both issues of the origin of network platforms, dating back the era of Avant-garde orMuséeimaginaire, as well as the current status of Institutions in the network era, to conclude with questions about architecture of presentation or manner of distribution of re-formulated works of art in the Internet world.
