A bittersweet piece in New York Times about the amazing work of homeless artist Anthony Horton (who died in a subway fire) done from charcoal and fax machine ink he found in the trash. Excerpt below:

Mr. Horton found solace in the blackness of the tunnels. He made the subway the subject of his canvases, the muse for a graphic novel that he co-wrote, and the place he called home for the better part of his adult life, even when he had other places to stay.
