Digits 1-9 show up by the 13th decimal place of pi, but the first 0 does not appear until the 32nd decimal place. For the first 13 places a new digit shows up every digit or to), then 20 places go by before the first 0 appears. That seems very odd if the digits are randomly distributed. But I guess that's the nature of true randomness. Its results are far less uniform that we expect!
