She has worked in many media including "tapestries" in which she weaves black-dyed wool into linear patterns; sculptural work using plaster, concrete, and lead; and photography. In 1980, Lafontaine started using video in her sculptures and has created installations and environments utilizing video.[6][7]
She was awarded the Prix de la Jeune Peinture Belge in 1977;[8] a FIACRE grant from the French Ministry of Culture in 1986,[9] and in 1996 the European Photography Award.[10][2]
Critic Konstanze Thümmel describes the dominating themes in her post-1980s video work as "association between Eros and Thanatos, passion and reason," and that Lafontaine explores these "...through powerful images of people and animals in extreme situations."[11][9]
