Spark: Felipe Dulzaides

If Felipe Dulzaides has his way, his art will make people question their everyday environments. Spark talks to him about his public art piece, "Double Take: A Billboard Project," a collaboration with New Langton Arts consisting of eight billboards that were installed throughout San Francisco over the course of a year from December 1, 2004 to December 31, 2005.
