Nashville’s Hammock Publishing has a 16-year-old annual tradition: giving T-shirts to the people they work with throughout the year. This year they added a new twist to that tradition: T-shirt+Photo=Laptop.

If you received a T-shirt, Hammock asked you to add a photo to a world map on their website. For every five photos added to the map, they donate a laptop to the educational efforts of the One Laptop Per Child Foundation in developing countries.

Kudos for a very cool way to help kids!
