Ok, so this was my final-year project from university which I finished working on around easter, but because it was a marked piece of work I couldn't post it online at the time, though I think it's safe to post it now. I'm not sure how interesting people will find it - its intentions were always more scientific than videogame-ific, though I'd like to think it could apply to videogames somehow.
Below is a link to a webplayer of one of the scenes from it, though that page also contains links to the unity source (using which you can access the rest of the scenes) and the write-up. Controls are listed at the bottom of the page.
