painting rooftops

it's not a completely new phenomenon - painting the rooftops of buildings to advertise to the skies. typically you find these places around airports, creating advertising for a nicely targetted crowd. however, apparently people have been seeing these things on google earth that aren't really close to any airports. this has all sorts of interesting implications for the evolving ways of navigating through and seeing, in both the literal and nonliteral sense, our landscapes.
