CrispMe presents the Underground World by Valerio Loi:
A very common way to cover long distances in London is definitely the underground, or better to say, the tube. Many of us commute to schools, universities, workplaces, also tourists travel on the underground to go visit places all around the city; basically a great deal of people find themselves using the tube nearly on a daily basis, making it very busy during rush hours.
My attention has also been caught by the geometry of the underground spaces, their nearly (sometimes perfectly) symmetric appearance is something very pleasant to be caught into photographs.
