Physical randomness is better than computer generated pseudo-randomness. The easiest way to generate physical randomness is with dice. To create a Bitcoin private key you only need one six sided die which you roll 99 times. Stopping each time to record the value of the die. When recording the values follow these rules: 1=1, 2=2, 3=3, 4=4, 5=5, 6=0. By doing this you are recording the big random number, your private key, in B6 or base 6 format. You can then enter the 99 character base 6 private key into the text field above and click View Details. You will then see the Bitcoin address associated with your private key.
