This is what is known as The Lost Experience, a number of events to do with Lost outside of the TV show from Hanso Foundation adverts in papers to the Hanso Foundation website. JJ, and the boys and girls at ABC marketing have released 70 clips over the net for people to find, and to sort into order. This is the edited version of all 70, on YouTube. Big thanks to Timdorr for dedicated collation and orientation :-)
Be warned, this has spoilers a plenty (but won't spoil too much for you).
