On May 15, 2012, Aday.org asked people around the world to pick up their cameras to photograph daily life. More than 100,000 images were submitted from 165 countries, by both professional and amateur photographers.
Behind the idea was the Swedish non-profit foundation Expressions of Humankind, whose mission is "to use the power of photography to create, share and inspire perspectives on daily life – today and tomorrow."
And now they've brought out a beautiful coffee-table book filled with breathtaking images from a single 24-hour (plus time differences) window on the planet.
