Robert Filliou declared that Art was 1,000,000 years old on 17 January 1963, the date of his own 37th birthday. Filliou has been said to suggest that on 17 January 998037 BC, Art was born ‘when someone dropped a dry sponge into a bucket of water.’ A global network of artists and friends have since celebrated Filliou’s vision of undifferentiated ‘art’ and ‘creativity’ annually on this day. Art’s Birthday epitomises the capacity of the The Eternal Network for shared creativity and play, for the celebration of ‘art’ and ‘life’. This global event has also been a context for developments in networked art practice over the last fifty years. Local meetings of artists and friends across The Eternal Network have been connected through forms of conceptual, postal, fax, telecommunication and online art practice. It is then an important opportunity to maintain continuity with practices of the past while developing new creative strategies to our own times globally. Art’s Birthday is significant to this research in providing opportunity to research an unusually long-term annual networked art event involving a wide range of people, practices and media. It is also continues to offer a context for practice-based curatorial experimentation during the research period itself.
