Virtual dollars trading for U.S. currency

Linden Research's online role-playing environment "Second Life" is developing a life of its own, offline. Linden Labs CEO Phillip Rosedale points to a community of people who have started businesses making and selling goods and services specifically for this virtual-reality world.

"The Linden dollar currently trades for 230 to 1 against the U.S. dollar," according to Rosedale. In this video, correspondent James Hilliard takes a closer look at "Second Life" and its latest animation upgrades, released last week.
