We've always wondered what happens to a package when we drop it off at the post office -- and having received our share of oddly damaged parcels has only heightened the mystery. British artist Tim Knowles was similarly curious, and his latest piece, "Spy Box," is a clever attempt to document the journey the box took from his studio to a nearby gallery. Knowles rigged a camera inside the box to take a photo out of a small hole every ten seconds, and stitched the resulting 6,994 photos together to make a short movie of the box's 19-hour journey. The end result isn't too thrilling -- the box is in a room! The box is in the dark! The box is in another room! -- but it's still pretty interesting. Peep a short clip at the read link.
