"We're All Gonna Die - 100 meters of existence"
"This image is 100 meters long (100m x 78cm)
There are 178 people in the picture, all shot in the course of 20 days from the same spot on a railroad bridge on Warschauer Strasse in Berlin in the summer of 2007.
Only a few of the people in the photograph seemed to know I was taking their picture."
