Are there Bitcoin password crackers I can use to recover forgotten passwords?
Revalin made available a sript that you can try running:

There may not yet be anything else, but you'ld probably find someone willing to write one if you offered to send your wallet along with what you think the pass phrase might be and ask only for a fraction of the wallet's bitcoins back once cracked.
