Google Maps gives handy driving directions from city to city, anywhere in the world. Large bodies of water prove no object either, with instructions to "Swim across the Atlantic Ocean" (29 days, 0 hours) when requesting directions from any US city to any city across the pond in Europe.

Unfortunately, the Google programmer with the sense of humour hasn't extended the joke to transtasman travel. And when I requested driving directions from Auckland to Christchurch, it actually told me to catch the Interisland Ferry, and correctly calculated the travel time. Which, I admit, is probably more useful than amusing instructions to get my togs on.
