NeilThanks for watching – all the best to you and yours – yes, I am hoping to go to the Nottingham RDH event – always a good, educational 3 hours (even for me!)Re the Aztec head, http://mars.jpl.nasa.gov/msl-raw-images/msss/00184/mcam/0184MR0925102000E1_DXXX.jpghere’s what I wrote to someone elseI loaded the original into Paintshop Pro and had a quick fiddle. The “eye” is interesting, but the “teeth” are almost certainly an effect of image compression/tiling – you can clearly see the tiling on the original image if you zoom into it enough. It’s possible the circular feature is from where the rover drilled into a rock… Quite interesting though…
