As I continued my cold tour yesterday, I discovered this striking piece in front of a condo building on Bay St. Titled "Liquid Echo", this work of stainless steel, aluminum, and concrete was designed by American-born artist Catherine Widgery and was installed in 1999. It is an environmental piece with each of the 24, 20 ft high tubes being wind driven to create the effect of a waterfall when in motion. Only a few were spiralling yesterday - will have to return on a windy day in summer! I featured one of Widgery's works before - here.
