2ToTango is an 8-foot-long polished-aluminum seesaw-like bench that creates observational and social interaction opportunities. Simply behold its beauty, or sit on it and experience cooperative, dominating and/or engaging interactions. 2ToTango is envisioned to be installed in public places, with museum environments being the most likely setting. Its triangular cross section twists 180 degrees. It provides flat surfaces for seating, and the sharp edge in the bottom center of the two middle segments creates a visual fulcrum.
