This is a video that Ivette Lake shared with me. It reminded me of a stunt pulled in Grand Central Station. That stunt involved a large group of people who, on a signal, froze in place. They became like statues and caused all the regular commuters to come out of their typical commuter mindset and stop to observe the world around them.
As near as I can figure, this video was filmed at a train station in Antwerp, Belgium, and puts the New York stunt to shame.
