From the Mud on the 'magic carpet' could prove that there's life on Mars thread (my comment is in post 15 in that thread):
Note the "conch-like" thing lower-center. Since that was posted, I've found a better reproduction, it's been balanced to get rid of the red cast, and it's larger. The caveat is that I found it on a "tinfoilesque" site, but since it's just a plain ol' "corrected" photo (as I'd do myself if I had my image editor re-installed since The Crash), and I'm not going with any of the guy's "machinery in the rocks" nonsense, I don't feel any qualms about pointing to this photo:
Several other interesting things in that photo, IMO.
The same guy also found another "conch-like" thing, and put a comment of his own in the photo. (Maybe someone can find the Nasa original if they'd like.):
What he didn't spot is what looks like another eroded spiral shell, to the far left of the one in the photo. It's more eroded, but you can stll see the "hub", at about the 5:00 position, and the remains of the "core" of the spiral.
Here's a closeup he's got of the one he did see. The "hub" looks pretty obvious to me:
Here's one more, from The Mars "Thread" Thread.
In that picture, the item to the "southeast" of the big sphere in the lower-left of the picture looks like a tiny spiral-shell, looking down from the top (or up from the bottom), i.e., "hub" on top, and "chambers" surrounding it.
Maybe these spiral "things" with the obvious "hub" and "chamber" sections are "just rocks", but so many of them found in such a short period of time would seem like quite a coincidence to me.
And for the record, I am someone who has taken a very cynical view of the "rorschach kids" who see everything from rusty tanks (rocks) to "buildings on 'Twin Peaks" (jpeg artifacts) in the photos from Mars. I wince as I post this, fingers crossed that I won't be categorized as "one of them" (because I'm not!)
Just trying to clarify it, lest someone think that crystal clear, razor sharp picture pasted onto the red-toned somewhat blurry mars-shot if part of the mars picture. (And, lest I get bashed over the head by someone who might see it later, and not see what to me is obvious.)
Ah, there we go. Caveat, caveat, caveat, you're all informed now. (Apologies to the Firesign Theater, and now I'm off!)
