One of my co-founders hacked something similar together in JS using an different technique a few years ago, but never got around to going anywhere with it: http://www.zettabytestorage.com/gloam/
I don't think it's been touched since sometime in 2008, but it's still fun. (Though notably more primitive)
Edit: The website for it is rather sparse and stale, but drop us a note at 'support' at the above domain name and it'll get to the original author of the code.
Edit: Also, not trying to steal your thunder or anything, what you're doing is different and new, what I linked is quite unmaintained. Just pointing out some similar work who's author I know well, and who might be fun to have chat with about it.
