ingredients:

• pen/pencil for writing: 1
• paper to write on: as much as rquired
• 16-sided hexadecimal dice: 1
• an even ground to roll the dice 64 times: as big as possible!

congratulations you now own a private key. not to get your bitcoin address you need:

• some tool to convert the hexadecimal result to a bitcoin address.
• a DVD with live linux to run that tool

now you are only trusting ECDSA and hashes to be safe.
