Toroidal topologies are found in tornados, whirlpools, vortexes, and magnets. They have come to symbolize the movement of the Earth within the solar system. Floating this architectural vessel on the water directs our movement around a continuum, echoing the watery pathways it rests upon. Torus was a 60-foot-wide closed curve tunneling over an arrangement of steel sectional barges. Just prior to sunset, Torus was tugged to shore and tied to a pier, where it was docked for the night. As the boats departed, a circular ceremony began. People were invited to walk in and around the floating Torus and enjoy a serene space as the sun set. Organized for Nuit Blanche, Toronto.
