Giant Pallet Wood Map

While walking around Grand Rapids Michigan during Art Prize, I came across this enormous map of the United States.  Upon further inspection, it was made entirely of pallet wood! They used different distressing techniques, angles and shading to indicate different states.   I'd love to see a reader make a replica of this ;)  On another note, Art Prize in Grand Rapids was a pretty cool event.

Pardon the poor quality cell phone image.
