Random.Org

RANDOM.ORG produces the highest quality true random numbers and makes them available to the world in useful forms. RANDOM.ORG's randomness comes from atmospheric noise, which for many purposes is better than the pseudo-random number algorithms typically used in computer programs. People use RANDOM.ORG for holding drawings, lotteries and sweepstakes, to drive games and gambling sites, for scientific applications and for art and music. The service has existed since 1998 and was built by Dr Mads Haahr of the School of Computer Science and Statistics at Trinity College, Dublin in Ireland. RANDOM.ORG became a Limited company in October 2010.
