project idea

I think the digital world environment can have a lot of educational applications. I am specifically interested in using it as an ESL tool -- an ESL garden if you will where your avatar can walk through a virtual space in which certain objects and situations will present an opportunity to learn new vocabulary or practice existing vocabulary. I am trying to work out how to do this without breaking the immersive feeling of the game and how to allow avatars, and consequently users, to learn from each other.
