Well, I'm officially stumped. Here is what I have so far...
I ordered the Moon Grotto 7" vinyl to "keep on digging" as instructed by the transmission phone number.
The vinyl is sleeved inside 1 of 2 puzzles One is the grid on the iPhone here: http://superbrothers.ca/moongrotto.html
There are two points at which the grids are different: spot 77, and spot 92. When these numbers are input into the phone at the website they give "secret grooves??" and "itself = 1977"
The aforementioned secret grooves when played on the turntable say "itself times itself, three times" and "itself minus a billion + 1." Entering the resulting computations into the phone gives a link to a video, http://vimeo.com/46508916
and a corresponding password, "voyager". The video has a quote from Carl Sagan.
I have no real ideas on what the video means. The other puzzle is the maze on the vinyl itself also shown on the moon grotto page. I also have no real idea how to approach that either.
I have toyed around with audacity playing the moon grotto song backwards and heard a "can you hear the moon in mono." By changing the audio to mono i heard "/burnapalefire" which led me to discover this: http://www.superbrothers.ca/burnapalefire.html.
It just plays the music from the #moar achievement. It is transcribed as follows:
Ladies and Gentlemen, we've heard your cries, and we apologize for the delay.
What kind of adventure is this?
Your subconscious knows the truth.
You are now among The Initiated.
Day and Night are in balance.
Long Live The New Flesh.
I wonder if there are woods out there?
...If those woods need woodsmen...
...If those woods need chopping...
Itself times itself three times.
See You in Heaven, High Five.
We will meet again at the appointed time.
I thought I heard something in the record.
I'll forgo typing all of the See You In Heaven, High Fives.
I wonder if there are woods out there...?
...and if those woods need woodsmen...
...and if those woods need chopping...
A bunch of Now We Are Cosmic Friends Forever
I have no idea where to go from here. The name of the secret video being ?" and the mirror image of the space ship at the 11 second mark led me to believe perhaps the maze needs to be inverted as if in a mirror, but I have no idea how to apply that information.
