A cold mist is hovering over Hackney today. Fewer people seemed to be out with their dogs, though it could also have been the timing of the satellite pass. However a group of people had gathered on the far side of the open field near Downs Road, bikes fallen sideways on the grass. They were stood in a wide circle doing slow movements with their arms and legs. As they were mostly dressed in long puffer coats and thick scarves, and because of the blurring fog, they looked like people made of cushions or marshmallows, moving slowly in coordination.
