If you don't take the subway and walk from the 1, 2 or 3 into Port Authority you may have missed this ingenious billboard display. Its an ad for Big Love the HBO series. The ads, light from behind like many nowadays, actually has small ports so passersby could plug in their iPod ear buds and listen to the "thoughts" of the people in the ads. Absolutely brilliant. And yes, I did see people listening in!
