Armchair scientists, get out your keyboards
Since it seems that we all love a bit of mystery, here's a fun story for everyone.
NASA's hard-working little rover, Spirit, took some photographs on the Martian surface over the span of a couple of days back in November. In one of these images, there appears to be some sort of rock formation that closely resembles a man strolling about steadfastly on the planet's surface.

At first glance, it definitely looks like a human shape, but after looking at it for a while, it looks like the bottom part of the figure blends in/is connected somehow to the rock behind which it appears to be. What are the opinions of my fellow armchair scientists here?
