David Kessler is a Philadelphia artist of many talents.

He is a filmmaker, recently making a documentary about Zoe Strauss, taker and seller of beautiful $5 photographs under I95. A collaboration between the Institute of Contemporary Art and the City's DHS, eight foster children worked alongside David to shoot the film. Their self-depiction of their experiences led to conflict with DHS, delaying the wildly successful screening of the movie.

He can paint and draw, sketching portraits of the overnight customers of the Broad and Christian Dunkin Donuts night after night in fine-lined pencil.

He designed crazy "Crazy Straws" (a Philadelphia product, who knew?).

And now he is posting a year's worth of gorgeous, intense, moving, challenging conversations with people who work, live, pass through, and spend time under the El train.

You can watch them here at his website "Shadow World: An intimate look at a place where time is measured not by the movements of the sun but by the rumbling of the el train. Philadelphia, Front St./Kensington Ave".
