sol 123 OM69 animation of,er, uh...uh:

with links to all kinds of different presentations, including this EDF ( extended depth of focus ) 3D.

Rocks. Yeah! That's it: bumpy, transluscent rocks rolling around on a pile of immobolized soil... with hooked tails. That's the ticket.
Here is a sol 123 EDF montage comparison with a sol 29 montage -- with links to EDF 3D images.
You might want to search my Flickr images with the search term Phoenix EDF 3D to see the other EDF 3D I have produced so far.
