I think the "autism world" idea might be pretty good. It does sound interesting, anyway. I'm not too keen on the Environment app, doesn't sound quite as interesting really. Doing a project like this is a really great idea, and I'm sure you can get a good level of detail within a two year timeframe, although this could be deceptively short ![Smile :)](./images/smilies/icon_smile.gif)
