After weeks of idling, Lost finally gave us a juicy nugget in last night's episode. It came in the form of a glow-in-the-dark map on the inside of a blast door. It appears to be a map of all the Dharma Initiative hatches on the island, and something in the middle signified with a giant, pink question mark. It looks as though all the hatches were meant to lead to that middle spot, but they weren't finished or were blocked off (as marked with X's). Maybe that's what the concrete is that Jack and Sayid found.

According to this guy, who evidently stayed up all night decoding the map, it has several phrases, such as "Sursum Corda", and "I Am Here" on the Swan hatch (where the characters are). There are several other phrases that I'm guessing are in Latin.

Here's another, deconstructed version of the map with a lot more text (somebody has Hi Def TV!).

What do you see?
