Wolfgang Staehle (born 1950) is an early pioneer of net.art in the United States, known for his video streaming of the collapse of the World Trade Center in New York City during the September 11 attacks.
It started out as an independent media project that began as a bulletin board system (BBS) that later became an online forum for artists and cultural theorists to exchange ideas.
He documented it by setting up a digital still camera at The Thing's office located in New York's West Chelsea neighborhood.
Every four seconds, the camera took a picture of the building and the images were sent and projected in a gallery at the ZKM Center for Art and Media Technology in Karlsruhe, Germany.
[3] Staehle has continued working on his series of live online video streams of other buildings, landscapes and cityscapes such as the Fernsehturm in Berlin, the Comburg Monastery in Germany, and a Yanomami village in the Brazilian rainforest.
