From Gizmodo, these photos and more:
The first one [above] is an intricate network of what appears to be huge metallic stripes. Is this a military experiment?
…It covers an area approximately one mile long by more than 3,000 feet wide.
…The third one [above] I don’t know what the hell it is either, and it’s perhaps the craziest of them all: Thousand of lines intersecting in a titanic grid that is about 18 miles long. Another targeting grid? A big practical joke?
See the wackiness in full.
