General Discussion - Flashcard Fish Program?

Hey all,

I am looking for a resource that I believe was posted on here not long ago, maybe half a year ago.  It was a flashcard game in which fish would swim down the screen and you had to type the pinyin for the character before the fish reached the bottom.  You could use your own text file with Chinese characters.   Anyone know?

Or has anyone got any other good recommendations for character flashcards that one can share with others, and use their own vocabulary files?  Trying to put together something for my class here at Edinburgh for the book we are using.  Thanks!
