An email invitation to walk nine laps on the crosswalks of a road intersection.

"Your orientation for the laps (clockwise or counterclockwise) will be determined by which light is green when you arrive at your particular corner. Once walking you should use only functional conversation (this means no aimless chitchat) and your behavior should not deviate from ordinary pedestrian behavior."

Friends walked their nine laps and reported back on their experience. The above video was made by the Brandel family, documenting their nine laps in Berkeley California.
