Not too many years ago, people who carried on conversations with folks the rest of us couldn't hear were considered demented (or drunk). Then came the cellular phone headset, which meant normal people could walk along, carrying on conversations with people we couldn't hear, although many researchers came to believe that a large percentage of so-called "normal" cell phone users were also demented (or drunk). Now Google's Project Glass means people can walk along, seeing things no one else can -- and carrying on conversations with them. Are Google's Project Glass users demented? Are they drunk? Or are they looking at heads-up displays mounted on glasses frames or attached to prescription glasses? Inquiring Slashdot editor Timothy Lord wanted to know, so he joined a Glass demonstration hosted by Google co-founder Sergey Brin (whose company is not related to Barney Google, as far as we know) to find out for himself -- and to share his findings with you.
