The countdown timer at CompleteThePattern.com ran all the way down (again), and it appeared that there was no change to site. However, the entrance to "Phase 2" was found, thanks to FringedOutChris and Chris Lynn.
By surfing directly to CompleteThePattern.com/Phase2, you are taken to the new content, which includes a behind-the-scenes clip from the Fringe Season 1 Blu-ray And DVDs, downloadable wallpapers and themes, and a chance to win a trip to the Fringe set in Vancouver and other great prizes.
Warning: According to the official rules, the contest does not officially start until Monday, August 24th - so enter early at your own risk.
There is also a very simple "Pattern Test", which if you complete (i.e. Complete The Pattern...), you will get five more entries into the sweepstakes.
