Dead Drops is an interesting physical digital crossover from Aram Bartholl:
‘Dead Drops’ is an anonymous, offline, peer to peer file-sharing network in public space. USB flash drives are embedded into walls, buildings and curbs accessible to anybody in public space. Everyone is invited to drop or find files on a dead drop. Plug your laptop to a wall, house or pole to share your favorite files and data. Each dead drop is installed empty except a readme.txt file explaining the project. ‘Dead Drops’ is open to participation. If you want to install a dead drop in your city/neighborhood follow the “how to” instructions and submit the location and pictures.
Aram Bartholl has also developed this into an exhibition piece for MoMA in New York.
