If there's one thing to be said for Curiosity's mission on Mars so far, it certainly hasn't been boring. From supposed Martian squirrels to strange flashes of light on the surface, the rover has kept us entertained. And now there's this rather odd... ball.
Take this recent photographic example from the Mars Science Laboratory's Mastcam camera that was uploaded to the mission's photo archive on sol 746 (Sept. 11). While compiling a mosaic of images of the surrounding landscape, Curiosity captured a rather un-Mars-like shape atop a rocky outcrop.

At first glance my brain is going WTF ???
But reading further down in the article, it's only about 1cm, the size of a marble, and it's at the bottom of a 3.5 mile high mountain. I can see how it could have been weathered out of softer rock and rolled down the hill.
Cool picture for sure.

While that's possible, I see no evidence of it having rolled downhill.
