What you see here is part of an art project called Dead Drops. USB drives are stuck into walls around New York City and users are encouraged to connect and upload and download whatever they want. Knowing New York these things will soon either be coated in slime or filled with chork porn it’s definitely a fun project.
The devices are at the following places:
Each drive contains a readme explaining the project and there are will be updates on the project website. My favorite is this shot of our buddy Bre Pettis getting his drop on.
