Saw this blog post with a video of a Spaceship Yamato converted to an R/C submarine and being driven in a swimming pool.
I'm definitely at a loss for words in admiration of the skill of the modeller. Check out more projects of their's here.
I loved watching the Yamato series as a young boy, too bad that because of my youth I couldn't understand what the anime was all about. Would love to watch this again.
