One of the many technologies Google talked about yesterday on Day 1 of its three-day Google I/O conference is Project Glass, a wearable computer of sorts that essentially integrates the functions of a smartphone into a pair of slim glasses. A rather exhilarating demo showed a series of stunts captured on video by people wearing the glasses, from skydiving over San Francisco to scaling Moscone Center, and you can't help but get at least a little excited seeing the technology come to fruition right before your eyes. We're not talking 10 years from now, either. In fact, programmers attending the conference have the option of pre-ordering an "Explorer Edition" prototype for $1,500, which will ship out early next year.
