v2.6.2 support input of a private key in base6 format which shall be defined as:
99 characters (1,2,3,4,5,0) where 1=1 and 6=0

This allows you to create a private key with physical randomness with 99 rolls of a die. Use 3 dice and do 33 rolls.
Then enter the 99 character string into the wallet details tab of bitaddress.org and you've got yourself a truly randomly generated bitcoin wallet.
