RANDOM.ORG - True Random Number Service
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.

Welcome - RANDOM.ORG
This is fine for many purposes, but it may not be random in the way you expect if you're used to dice rolls and lottery drawings. RANDOM.ORG produces true random numbers from atmospheric noise, which for many purposes are better than pseudo-random numbers.

Introduction to Randomness and Random Numbers
RANDOM.ORG is a true random number service that generates randomness via atmospheric noise. This page explains why it's hard (and interesting) to get a computer to generate proper random numbers.
