"Factory Moe (kojo moe, uncontrollable love for factories)" for you.
The beauty of the pipes, fire, lights, and smog are one of the best artificial beauty for some people. What they have is all about efficiency, and now it becomes beautiful artwork. Stay out of the restricted area, and find your own best spot!
