Multimedia Project - Learning other languages

I would like to create a multimedia project using flash in which users can learn other languages. I’ve heard Flash can be very effective in developing this type of learning.

So say I want my English users to learn French. The way to go about would be have a predefined set of sentences/words/letters in English and button that states, translate this sentences/words/letters in French…easy right…

But I would like to make my multimedia application more appealing, more useful, more in content, sorry I work for a university and we are suppose to develop instructional/learning multimedia projects on CD/DVD…

Any thoughts or ideas as how I can make this project look “cool”, I mean important in content or useful or any other projects that I can do…

Thanks for reading it…

cheers
