That was very cool. Have you seen the video (may be at the same station) where some silent cue is given and all the participants freeze in place with whatever they were doing? One guy had dropped some paperwork and was bending to pick it up, other people were in odd positions. They all held it for about 2 or 3 minutes. The folks in the station were going nuts, calling to tell their friends what was happening and then on another silent cue, life returned to normal.
