I see constantly the use of "morphing" in Martians sculptures. Please look for that when you look at Curiosity photos. Especially the Mascam ! Seems like they are developing the story line with imprints in the #2nd one. Notice how strange little objects protrude out of the 2nd "knuckle" like form!
The analysis I use for the photos and imagery are not mean't to be exacting, only to get you closer to understanding that there is intelligent life on mars (martians). Many of the rocks you may think are rocks, are in fact highly designed sculptures, mechanical objects etc.
Nasa is trying to leak out anomalous imagery with out of course talking about it public! Though most images have been doctored, Nasa is trying to humbly and quietly nudge us along with out going too public about it vocally. Though it is work and painstaking effort to find objects in the images that have not been altered in some way!
