Hi Levelwind. I particularly like the rectangular middle one of the 3 images you posted. The shadow beneath shows very clearly that it's a thin folded material, not a rectangular chunk.
I hardly ever look at Opportunity's images. It's a good find.

Levelwind.I was going to say that glassy materials fracture in this irregular way but then took a good look. Yes it's a good find, here's a few bits I noticed to add to yours. Well Found!
Noticed the blanked out bit using this filter (above) This reminded me of this: http://bp-web.baypath.edu/biology/sheep%20brain/brain-sheep.html see VENTRAL VIEW
This one is auto whitebalance in gimp
From auto white balance above
the area blanked out doesn't show

What I believe to be electrical power lines with insulation that has degraded. In the centre of this image, if you zoom in, is a small machined part with it's empty casing beside it.
Thanks for checking my post out, Goggog really hit one out of the park. I attempted to draw more detail out of the pic he submitted by layering it. There is also something "creeping out" of the object he highlighted. This thread is killer thanks to all the contributors.
