SYLVIA STONE

From AskArt.com:

Constructivist sculptor Sylvia Stone was born in 1928 in Toronto, Canada and is known for her large-scale sculpture with environmental themes. Her preferred mediums are transparent plexiglas and opaque acrylic sheets, sometimes as long as 30 feet. She began this type of work in sculpture as a transition in the 1960s from working with shaped paintings on plastic. Her motive, a reaction from an unhappy childhood, was to "create a poetic, aesthetic environment as an alternative to the real world and present the spectator with the illusion of a fantastic architecture, which can be entered." (Rubinstein, 366).
