Yahoo Mail may not be the coolest webmail service around, but it's one of the biggest. The new Yahoo Mail, while still hated by some people, is rather slick and pretty useful. It's also very purple.
In an effort to recover some of that "coolness" or just get people to remember that they have an Yahoo account, the company has gone old school and put a literal mailbox, a purple one at that, on the streets.
It's no usual mailbox either, this one has a voice of its own, again, quite literally. Apart from scaring people walking down the street, it does have another purpose, handing out all sorts of gifts for those who take the time to talk back to it, from iPads to Super Bowl tickets.
