There are all sorts of websites out there, the one broadcast in the most recent LOST episode fake Hanso commercial points you to www.sublymonal.com where you can "unscramble" a code (the code is HEIR APPARENT, it takes forever to get that, so just take this nice little short cut I'm giving you). Unfortunately, it doesn't give any info as to where to use this code. I suppose we will have to wait for next week's LOST or something.
This is wild and wacky stuff. There are websites with easter eggs, phone numbers with messages, all kinds of fun stuff to keep you distracted or hooked into watching the show.
Some of the wild and wacky stuff:
There was a Dharma symbol on the plane, shown in the first episode on the side of part of the plane.
There was one of the Dharma symbols on the tail of the shark that attacked Sawyer & Michael while they were adrift at sea.
There are more wild and wacky things, but you are going to have to find them for yourselves. My melatonin has just kicked in, and it's time to go to sleep!
