sol 32 animation of 8 hours of lighting changes in rock and soil near Phoenix:

This was created from 21 RAC images in 7 time blocks.
Er, I will not comment much, save to say that you have to give your mind time to digest this animation.
One of the oddest ( to me ) changes is a very thin straight line that brightens and then dims ( top center edge ). I think it is "real" -- but real what?
There are a number of interesting soil circles which seem to be very tiny mounds with rings of tiny stones on the circumference.
Maybe mini versions of the polygons?
Mars. Damn queer place.
