Danish photographer Simon Høgsberg spent 21 months shooting 97,000 images of people outside one Copenhagen supermarket. Høgsberg began taking pictures in April 2010 outside a supermarket called Føtex — fascinated by the varied sea of humanity that passed him by each day.

Then he cataloged the images and plotted the intersections of people who featured in multiple photographs on different days. The result is a visual map of the lives of around 450 people who randomly cropped up multiple times during his obsessive photo-shoot. Høgsberg titled his work The Grocery Store Project. I’m still grappling with the value of this huge undertaking, but it is wholly fascinating nonetheless.
