No, this isn't a set piece from J.J. Abrams upcoming Star Trek movie. It's actually a sculpture set deep in the woods by French artist Michel de Broin. Dubbed Superficial, it looks like a giant boulder covered in mirrors.

Reflecting the trees and dirt of the forest around it, it looks like something from another planet. But what does it mean? "In this play of splintered radiance, the rock disappears in its reflections. Because it reflects one cannot be mislead by its presence, yet we cannot seize it, rather it is the rock that reflects us." Oh… OK. I just thought it looked cool.
