Light Showers
Jill Anholt
A series of iconic sculptures integrated into a new park along Toronto’s waterfront visibly express the surrounding community’s aspirations to sustainability. Nine meter tall art elements display and celebrate collected and purified community storm water , lifting it from the ground to the sky where it falls as a textured veil of water into a channel that returns it to Lake Ontario. As people meander over bridges between the elements, integrated motion sensors trigger shifting light patterns in the water curtains, emphasizing the connection between local actions and distant effects.
Location: Sherbourne Park, Toronto ON
