I decided to interact with the wind. I placed the arch on a four-way pedestrain intersection, and created a structure with two sails that slowly rotate in the wind. As the sails rotate, two beams on the lower level of the arch rotate in sync with them, and determine which way pedestrians travel when they enter the arch. In this way, the arch conveys the feeling of free-spirited exploration, as pedestrians travel whichever way the wind carries them. I used imagery from sailing to help drive the concept of freely sailing and exploring whatever way the wind may blow.
