Smart nodes, CAFAM goes to the border, Crenshaw Cowboy

DnA goes to check out CAFAM’s timely show of art and architecture, The U.S.-Mexico Border: Place, Imagination, and Possibility -- and on the way encounters the installation of LA’s pilot "smart node." Will the streetlight of the future contain cameras, charging stations, speakers and sensors to detect gunshots? And we meet the homeless artist whose Los Angeles studio was a freeway on-ramp, until he was moved on.

Host Frances Anderton looks at design and architecture from a Los Angeles perspective.
