Founded in Paris by Helen Evans (UK, 1972) and Heiko Hansen (DE, 1970), both graduates of the Royal College of Art in computer related design, HeHe is an artists’ collective whose works aims to rethink the existing technological systems that surround us, namely transport, public advertising and pollution monitoring, to give them a new socialand critical usage. For HeHe, the city is an endless source of possibilities, not only to build the new but also to exercise critique, to reprogram its buildings and infrastructures, to make the invisible visible and to create new meanings that weave stories for its inhabitants. HeHe has been commissioned to make site-specific works for the Centre Pompidou (Air de Paris, 2007), Luxembourg European Capital of Culture (Transient City, 2007), V2 Rotterdam (2005). Their videoToy Emissions (2007), which documents a performance in the streets of New York City was included in the Lyon Biennale of Contemporary Art (2009) and was shown in Norwich last January at the Invisible Dust exhibition at the Sainsbury’s Centre for Visual Art. Their project Nuage Vert (Helsinki 2008), was critically acclaimed internationally and awarded three prizes: the Golden Nica in Hybrid Art at Ars Electronica (Austria 2008), the Green Prix at Zero One San José (USA 2008), and the Certificate of Honour from the Foundation for Environmental Art (Finland 2009).
