Thanks. I was just wondering if there was a similar open source project.

it works on Win, Mac and Linux - written in Python
FlashcardDB allows a choice between two spaced repetition algorithms: Supermemo's SM-2 (like Anki, Mnemosyne) or the Leitner System. New card decks are shared for free.
If you're looking to memorise a lot of data, it's definitely worth a look (runs on Mac, Windows, and Linux).
