Some sol 112 accidental 3D of the Martian soil - including this one:

Unfortunately, if you can't "do" side-by-side 3D, you can't see the disk shaped thingie or the long tapering rod.

Sometimes have to rotate the images and / or switch left - right to see the 3D but when you do, some interesting shapes spring out of the picture - like these ones.
