Finally something really interesting to come out of the labs at Microsoft...
I glanced at this yesterday and quickly passed it off as boring, weak, etc. Then I watched the video and really understood what it means.
It is the coolest idea, geeky or not, that I have ever heard of. The possibilities are nearly scary and I feel downright giddy when I think of possibilities of the concept.
Imagine if you could force everyone to spend a day taking photos of their environment.
