The hype surrounding the concept of Google's much-talked-about Project Glass may have hit its first peak during last year's Google I/O conference when stuntmen jumped out of a plane wearing the device, but the demonstration left many people wanting an explanation of what else Glass can do besides first-person photo/video recording.

Since then, we've seen a few admittedly awesome videos, including a DVF fashion show through glass, and more recently the brilliantly-executed "How It Feels" which went a bit further toward showing real-world use, but at SXSW today, attendees were given what might be the most informative (and exciting) demo we've seen yet.
