"What's this fuss about true randomness?" Find out:

Perhaps you have wondered how predictable machines like computers can generate randomness. In reality, most random numbers used in computer programs are pseudo-random, which means they are a generated in a predictable fashion using a mathematical formula. This is fine for many purposes, but it may not be random in the way you expect if you're used to dice rolls, roulette wheels and lottery draws.
RANDOM.ORG offers true random numbers to anyone on the Internet. The randomness comes from atmospheric noise, which for many purposes is better than the pseudo-random number algorithms typically used in computer programs. People use the numbers to run lotteries, draws and sweepstakes and for their games and gambling sites. Scientists use them for random sampling and as input to modelling and simulation applications. Artists use them to make art and music. The service has been operating since 1998 and was built and is being maintained by Mads Haahr who is a Lecturer in the School of Computer Science and Statistics at Trinity College, Dublin in Ireland.
