On June 21, 2011, the Posner Advertising team set out to the New York Stock Exchange to join other interactive community members taking part in a unique social experience called the iPhone Symphony. At exactly 11:45 p.m., scores of people gathered around in a circle and raised  their iPhones up high in the air, unifying a distinct and dense reverberating sound via an iPhone sound application developed by GROUP. The result was wondrous.
