That's the largest glitter ball [I'm told] in the world rotating in front of a massive rollercoaster. The patterns in the foreground are designed to break up the waves as they crash into the seawall it's perched upon. The sky was awful so I inserted a better one ;o) I wanted to make it look like it would roll down the slope and over the rollercoaster.
