Kevin "Fester" Gallagher took six months to hike the 2,181 miles from Georgia to Maine. Each day, he took 24 photos of successive steps. His film, Green Tunnel, consists of 4,000 physical slides scanned in and set to music, and provides the closest thing to physical exercise you're going to get today. It's also quite beautiful.
