Michael Snow's artwork commands attention, whether you're pondering his whimsical sports fans at Toronto's Rogers Centre, his landmark avant-garde film Wavelength or a piece from his famed Walking Woman series.

Now, a new exhibit at the Art Gallery of Ontario titled Objects of Vision explores the veteran Toronto artist's fascination with the notion of looking and framing perception.

Snow invites gallery goers to interact with some of the works in the show: to sit on, touch and approach several of the abstract, conceptual sculptures.

"These things are attempts at provoking an experience," he told CBC News. "One never knows really what people experience."

The AGO exhibit, the influential artist's largest solo show in 20 years, was organized in conjunction with his winning the 2011 Gershon Iskowitz Prize. The gallery counts 82 of his works in its collection.

Snow has created a wide range of art over the years, including sculpture, painting, photography, installation, experimental film and music.

"The argument could be made that he might be the foundation of all contemporary Canadian art," says art critic Murray Whyte.

Objects of Vision,or How to Look at Things runs at the AGO in Toronto through Dec. 9.
