With its Lakefront Kiosk competition, the Chicago Architecture Biennial is hoping to leave a long-lasting impact and legacy for its city. The ROCK, a submission from NLÉ Architects in collaboration with School of the Art Institute of Chicago, is giving the public the opportunity to shape that legacy. Throughout the course of the event, which opened on October 3rd, eventgoers are invited to Millennium Park to add value to the 1930s limestone rocks that will create the pavilion through carving, painting, performances and other unimagined processes.
