If you're into learning a new language or need help improving french or spanish vocabulary for school, this is an interesting site to try. It has visual/audio cues to help you remember words in your new language, and it's sort of built as a social networking 'game'.
Each word you're learning is a 'seed' which grows each time you come across and practice learning it. Eventually you end up with 'gardens' of words growing that will wither if you dont keep up your practice. There's also options to create your own learning course for others, among other things.

Haven't gotten too far into it yet, so i'm not sure how good it is or what all you can do, but the idea is interesting and so far it's ok. I'll be throwing the app on my iphone as well to play with.
