Etrog designed Canada's top film award in 1968, "the Genie" statuette (which was known as "the Etrog" until 1980) and has collaborated with artists such as Eugene Ionesco, Samuel Beckett, John Cage and Marshall McLuhan. His work develops a complex visual vocabulary that explores time and the permanent bond between the plastic arts, with architecture on one hand, and society on the other. Etrog explores spontaneous symbols, primal elements and the relationship between form and symbol. Sorel describes his art as "tension created by pulling together and pulling apart, with being stuck and being freed, a world of grabbing and holding on and losing hold... bringing shapes together but at the same time giving each an independence."
Etrog has received several important commissions, including those for Expo ’67, Montreal; SunLife Centre, Toronto; Windsor Sculpture Garden, Windsor, Ontario; Los Angeles County Museum, and Olympic Park in Seoul Korea. His work has been part of many group exhibitions at the National Gallery of Canada, Ottawa; The Carnegie International, Pittsburg; The Museum of Modern Art, New York, The Solomon R. Guggenheim Museum, New York; the Hirshhorn Museum and Sculpture garden, Washington, D.C.; Palazzo Vecchio, Florence; Musee des Beaux-Arts, Le Havre; Musee Rodin, Paris; Kuntsmuseum, Basel; and the Centre Georges Pompidou, Paris.
