The Electronic Frontier Foundation has its own version of DiceWare, complete with several different wordlists for randomly generating passphrases with dice.
EFF’s new long list, referenced in the directions above, is designed for memorability and passphrase strength. We recommend selecting a minimum of six words from our long wordlist, or when using any other list of this size. The more words you use, the stronger the passphrase. Different wordlists may produce passphrases with different degrees of memorability, but you don’t get a significantly different passphrase strength by using one wordlist over another, if the lists are the same length.
