Australia's NRMA Insurance has outfitted a Sydney bus shelter with a custom sound system that lets you choose the songs with QR codes, just to remind people that its coverage extends to things like custom sound systems. To get the thing to work, you have to like NRMA's Facebook page and then download an app. Provided the song selection doesn't suck, this is a cool idea. Still, I don't understand why people think bus stops are dull enough to demand interactive ads like this. Maybe it's just Baltimore, but between random conversations, crazy people, and loud public arguments, bus stops are the best show in town. Via PSFK.
