From the New York Times:
Imagine relaxing in a tiny private cove, on a lava beach near the mists of a waterfall. The sun is shining, a tropical bird cries somewhere in the distance and the cares of the working world seem a million miles away.
It’s an idyllic vacation spot, but the best thing about it is that it takes less than five minutes to get there from anywhere in the world. In fact, you can reach it without ever leaving your home. That’s because it exists not in any physical location but in one of the many virtual worlds that millions of people now travel to every day with the help of nothing more than a decent computer graphics card and a broadband Internet connection.
