Berlin native Aram Bartholl got an amazing fascinating idea when visited New York City. He left USB drives around different places at the city, just stuck into walls, concrete, random public areas.
The idea behind this action is that if you have a PC, Laptop or anything with a USB port, you can plug into one of these drives. By this, you can see what files people have shared, and continue to share your favorite files, movies, and music from your machine for other random passers-by.
