Eye of Odaiba #2 - Massing Study Models

So now that we have explored the context of the site, we move on to a conceptual massing study.  Remember the goal is to create a camera obscura, so at the bare minimum it must have a pinhole for light to enter and a projection room where the image is displayed for viewers.  Beyond that, just about anything goes, so here are 3 massing options that I'm exploring.

This first concept is paying homage to boat traffic in the Tokyo Bay, including the massive cargo ships that come and go from the neighboring docks.

The next concept is more like a lighthouse that combines a modern base for a projection room and a more traditional tower for the camera "eye". 

The last concept is like a futuristic lighthouse which stands nearly 50 feet tall and acts as a visual and observational beacon of the harbor.  This concept would be more monumental in form, but it seems less contextual to me.
