Photo of either the Opportunity lander or rover. You might have to load the image in something so that you can zoom in on it, but it’s pretty clear that the NASA guys liked to play with 'em as kids from this shot. (BTW, more full color Mars images can be found here.)
It still just gives me happy shivers to think that those are photographs of another planet. 
Toys on another world…their time has come at last.
