Actually, I've been bouncing this idea of using a submarine as a stage set for almost a year now, but I finally sat down to figure out how to do it successfully. Well, here's the result. The original concept came from the Beatles song about a yellow submarine and one of my own interest is ocean exploration.
This stage is actually a little bit more fiddly to use than my other designs and there's no real way to make it really easy to use. Some degree of customization is almost mandatory and it won't work with motions where the dancer needs to move around a lot. So please do note that this set is designed for people experienced in making custom set ups as well as those who are comfortable editing or modifying existing motion data sets.
It's hard to explain how to use the set in words; it really is best that you see what it can do by looking at the demo. So, that's where the download link will be too as well as the password

Should be a fun set though. Personally, I was surprised at how well it came out myself. Set comes with basic motion data to animate parts as well as illustrated instructions.
