<b>Hot: Google Street View</b>
Google first introduced Street View, a feature of Google Maps that let you explore street-level imagery, in 2007. At that time, it only included images of five U.S. cities. Fast-forward three years and now Street View has visited all seven continents, including Antarctica.
Check out the beaches of Brazil, the moors of Ireland and Antarctica's icy terrain—very cool stuff.
