Multiplayer online virtual worlds consume a lot of your time. It's important to put them down now and then and get out of the house to live a real life, but that's about to get more difficult; we can expect massively multiplayer online worlds to become available on our cell phones any day now. There have been a couple small scale examples already, but a company called GEMINI Mobile Technologies thinks it's produced a breakthrough product.
The product is called "the eXplo platform." It's a framework for 3D online environments running on mobile phones. Its features include customizable personal spaces (essentially player housing), messaging, photo sharing, shopping, and games. A few days ago the CNET News Blog took a look at S! Town, a product based on the platform. Initially released in Japan, it's headed to North America and Europe and will feature Facebook and YouTube integration for American consumers.
