3 MINUTES TO SEE THEM COME AND LEAVE - 15 SECONDS TO DRAW THEM

You start to see people about 100m away. They will have spent three minutes in your field of vision and travelled 200m. You have 15 seconds to see their faces. The more happens where you are, the longer you have. And things happen where either people come together or they run into each other. 1:20 scale for people. 1:150 for places.
