The World-Wide-Walks explore natural/cultural/virtual identities: mixed realities that encompass walking in physical environments and virtually surfing the Web. The first of these projects, The Walk Series , was initiated by Peter d'Agostino in 1973 as video documentation/performances. World-Wide-Walks / between earth & sky / Dun na nGall is a video/web sculptural installation informed by environmental arts and sciences and local knowledge. It is one of the five Lovely Weather: Art and Climate Change public art projects commissioned by Regional Cultural Centre/Donegal County Council Public Art Office in partnership with Leonardo/Olats: www.peterdagostino.net/WorldWideWalks/Donegal .
