another option?

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. Grin

There are no 16-faced Platonic solids. The only games in town are: tetra-hedron, cube, decahedron, do-decahedron, and icosahedron, which have four, six, ten, twelve, and twenty-sides respectively.

You may have other shapes with exactly 16-faces but it will mean there will be a bias to some outcomes more than others. You could use a 20-sided die and mark four of them as "re-roll".

These dice have a top and a bottom, each with eight sides, those being 45 degrees each. Top and bottom is an eight sided pyramid. Given that symmetry it seems reasonable to consider them as a combo of a coin flip (top or bottom) and a random one of eight.

Personally I think this is far superior to any method of computer-generating "random numbers." The simple reason is the certainty that you have that nobody has monkeyed with the subroutines, because there are none.
