A number of public agencies have decided to allow local artists to paint controller cabinets.  City of San Jose, for example, allows schools or neighborhood groups to paint the cabinets with art depicting local themes.   City of Oakland downtown business alliance pays local artists to paint the cabinets.  This is an example from the Telegraph/17th intersection in Oakland.  With permission from the artist, Elisa Carozza, the attached photo shows the first two completed sides of the artwork.  Elisa can be reached at kuhlframes@gmail.com and is open to opportunities to paint other cabinets.
