The sun is out and shadows are popping up all over the city. Katie Sokoler, who often lends her photography skills to this very website, recently put together a fun project in the same vein as her thought bubbles. She explains that she cut out human forms from black paper "and taped them onto the walls and sidewalks all around Brooklyn. I then waited for people to walk by and took a picture at the exact moment they matched up with their silly shadow." Check out all of the secret shadows here.
