"...Two months ago, over his Christmas vacation, Kermitt Quirk created the game Tringo within Second Life. It has become a huge hit and has earned him over L$1,000,000. But that was apparently just the beginning. The Wall Street Journal (alas, no easy linking) reported today that Kermitt has sold the real world publishing rights of Tringo to Sean Ryan's Donnerwood Media for "low five figures." They plan to publish Tringo for mobile phones and on the web."
This require some thought - I'm not quite sure how to analyse this beyond noting that it's pretty cool (and not talking about the obvious fact that SL is being used as a platform).
