Sol 199: amazing disappearing pebbles

Check out the Sol 199 microscopic images for Opportunity.

Look at pairs of images that depict the same "scene."
Notice that in many cases, the pebbles (or grains) are
moved or missing between the two images of a pair.

Also in some of the images, there is a worm-like feature
poking out from a hole in one of the pebbles.
