I just read a theory that the Unknown Dharma station (i dont think it
was referred to on the show yet, but the logo was on the ajira airline
website, and in a dharma email) may be the church that Ms. Hawking is
in (with the computer room/pendulum in the basement), even though it's
not on the island. The lamppost outside of the church resembles the
logo of the Unknown Dharma station. AND that logo is also on Ms.
Hawking's computer from a previous episode ('The Lie' i think?).

i think its unlikely that the church is that unknown dharma station,
but i think the logo coincidence is interesting.
