At long last, the full vision of this project is coming to fruition!
Attached below are two screenshots of the new wallet-generator that is currently in beta-tests.
The software will allow anyone to select from one of many designs (or a pre-printed SafePaperWallet kit) and print a sheet of beautiful wallets. Once it is launched I will offer the opportunity for any designer to submit designs for inclusion in the software.
The top part of the paper-wallet generator allows the user to enter their own private keys and also generates deterministic aliases using the format adjective-color-animal. This makes it easy to find specific wallets from a stack. The aliases and public keys are exportable as CSV, to make it easy to add them to an online wallet address book.
The bottom part of the page allows the user to select a wallet design for the background:
