The day London froze made a reality by 100's of volunteers. At exactly 3:30pm on a secret cue, almost everyone in the square froze. The few bewildered tourists didn't know what was happening. For 5 minutes the participants held their positions, and then magically everyone unfroze.
On Wednesday 14th March around 50 people attempted a mass freeze frame in a Manchester supermarket lasting four minutes. Five cameras captured the event.
