This is an original way of disaster proofing your pass phrase! Another similar idea would be to laser etch a QR code containing the pass phrase on metal. That way you can machine read it into your wallet. But this is still a very novel approach that is totally human readable. Nice work!
Thanks! I remember reading about a Steemit-User who lost his account with a few thousand Steem when his house burned down. Tools like this are perfect in these situations.
