Illustration of Central Limit Theorem

If you would like to see illustrations of what I meant when I wrote about how mathematicians say that so many random things must be distributed according to a Bell Curve then take a look at Lee Wilkinson's page which was mentioned recently on Andrew Gelman's blog. The essential idea is that if you add up enough random variables, no matter how they're distributed, the resulting random variable will be normally distributed—or, in other words, it will be distributed according to a Bell Curve.
