Interactive art/sculpture

This life-size sculpture of Oscar Peterson is located outside the National Arts Centre in Ottawa ON. His piano recordings are played 24/7, and can only be heard within say...4 metres of the sculpture. It attracts passersby as does the invitation to sit beside the figure on the bench. I passed it daily for a year and often saw people sitting beside him for a moment. Like the comment about public art in Chicago, the sculpture garden there is full of art to interact with.
