One of those "Who? What? Where? When? And why?" times

There are many questions that run through my head when watching this video, but at the same time I'm completely fascinated!  I want to know where one acquires 10,000 iPhone 5's, why they chose the newest iPhone model (why not the older one??), Why they spent so much of their time setting this up, What are they trying to accomplish?  Finally at the end of the video I just realized what they have done, they have completely fascinated me and then right at the end of the video flash their company name and logo.  Well now I just want to know who this company is and what they do, because they have managed to amaze me.  In my opinion these people are amazing, and they managed to slip an advertisement past me with out me knowing what was even going on.
