Nell Tenhaaf is an electronic media artist and writer who has been deconstructing the dominance of DNA rhetoric in Science since 1989. Moving from choice-based interactive works in the late 1980s and early 1990s Tenhaaf’s recent artworks – Flo ‘n Glo (2005), Swell (2003), UCBM (You Could Be Me) (1999) – verge on autopoietic systems which include the viewer as one element in continuous flux. In 2003, the Robert McLaughlin Gallery in Oshawa (Ontario) mounted a survey exhibition of fifteen years of her work entitled Fit/Unfit, which travelled extensively in Canada. Through her writing and involvement with the Vida/Life art and artificial life competition based in Madrid (Spain), Tenhaaf continues to contribute to the debates she and Catherine Richards began with the Bioapparatus in 1991.
