Thanks to @gamehawk's post here I found some nice links on diceware and passphrases:

- EFF's dice passphrases page is great and clear: https://www.eff.org/dice
- The Diceware FAQ, especially the "how long" part, are very interesting http://world.std.com/%7Ereinhold/dicewarefaq.html#howlong

Oh and maybe most excitingly is how nice and easy the EFF word list makes it. Just roll 6 dice into a shoebox, check which word corresponds to that. Do that 6 times and you've got a passphrase.
