Here's the seating chart page: [link]
All of the seats are clickable, but only certain ones, when you click them, cause a *different* seat to be highlighted green. Click that green seat, and it shows you a passenger name, and if you keep clicking while it's green, some random extraneous character-related stuff appears, kind of under the seating chart.
Toward the bottom of the seating chart, where all the row numbers are, if you click on Hurley's unlucky numbers, in order, one after the other -- 4, 8, 15, 16, 23, 42 -- and wait a moment or two, the seating chart area should go to black, and then a teaser for next season will come on. (It's really a crap teaser, it's short and it tells us pretty much nothing, and the footage is -- I think -- all from this season. But there is a thrill in finding it.)
