In the age of iPhones and BlackBerrys, printed calendars can seem a little, well, dated. Still, this striking monthly calendar caught our eye. Swedish couple Esa (a graphic designer) and Lisa (an art teacher) trolled the streets of Stockholm shooting photos of artful address and license-plate numbers. The pair compiled their findings into a yearlong calendar, turning each month into an eye-catching piece of collage art. The pages are shipped unbound, so you can hang them all on one hook or pin them up side-by-side for a full view of the months ahead.
