Daniel Horowitz sat down at his desk and began, with no particular purpose or direction, drawing on a blank piece of paper. That piece of paper turned into two, three, four, and eventually 365. A mixed media artist, Daniel's work has been featured in The New York Times, GQ, and The Wall Street Journal. He is now the cover illustrator for The American Reader. His 365 Series has been turned into a book (a limited print of 365 copies of course).
Update: Horowitz has since began a new marathon series of drawings which you can follow here: http://drawingdujour.tumblr.com/
