What really makes this promotion special are the lasers and gunshot sounds that project the installation beyond the walls and right to the audience. Very cool. The gunshot sounds were triggered by the laser motion sensors. The installation, created for the WWF was designed to draw attention to the fact that humans have driven hundreds of species to extinction, with many more on their way. By putting us in their shoes, perhaps they can change some attitudes. The underground passageway in Beijing is used by 9,000 people per day, which means a whole lot of people are getting this message.
