Watching Chris Kelley talking in Second Life and also sitting in a chair here at the convention center. A crowd gathered wondering how we were talking to someone in a virtual world. Chris and his group have done a great job using Linden Labs' virtual community to promote Siemens. His avatar somehow disappeared but we could hear him fine.
They are doing an event in about an hour with the University of Cincinnati and they will be seeing a live presentation and have audience participation. Go to the Siemens Second Life page for information how to be a part of the group.
