You're looking at Japanese artist Chu Enoki's artwork called RPM-1200, a diorama built from junk metal, old drill bits and spare machine parts polished into gleaming, shiny spires of a futuristic city.
The sculpture is actually pretty big, it measured 11 feet tall (3.4 m) and 15 feet (4.6 m) in diameter. As shown below, the details are absolutely fantastic!
