You can find sources of truly random numbers, though (and without having to roll dice yourself). Some newer computers have a random number chip that generates random data from amplified thermal noise. If you don't have one of those, Random.org is a website that supplies streams of random numbers, generated by radio receivers tuned to atmospheric noise. You can access these random numbers R by using the random package from Dirk Eddelbuettel. This is as random as you can get: there's no way to predict one number from the last.
But for some people, even that isn't good enough. GamesByEmail.com used to use Random.org to generate the dice rolls for various games played via email, but some of the players complained that the rolls "weren't random enough". (Incidentally, I've seen similar complaints in the forums of every computer strategy game I've ever played where the results of battles are decided by random rolls, like Warcraft, Advance Wars, and the Civilization series. You'd be amazed at the lengths some players go to to "prove" that losing a 20-1 odds-on battle twice in a row is always "biased".) So the site owner fixed the problem by rolling his own true random number generator ... literally. The Dice-O-Matic Mark III rolls 800 dice -- real, physical dice -- down an irregular, spiral ramp to be loaded into a bucket elevator where a camera with image recognition software reads the pips to generate a stream of random dice rolls. You have to see this monster in action to believe it:
So there it is the perfect solution for CC, get one of these machines and then no-one can complain http://gamesbyemail.com/News/DiceOMatic
