A chap named Martin Pirongs is walking a route that draws a large human figure inside the M25.
You can follow him live here: https://www.martinpirongs.com/m25-man-live-feedMartin Pirongs said:Taking a line for a walk, nearly 200 miles long. A unique connection with a city. Harnessing the art of GPS technology and the age-old power of walking - by pavement, path, road and occasional field - Martin is aiming to configure the outline of his own body, with his own body on a giant scale.
You are invited to witness the live GPS trail as it is created, slowly revealing an image that will inhabit the M25 and become the size of London.
