To my mind, bippy wins over similar tools such as bitaddress.org in a few ways. First, it can generate keys and addresses for multiple (45+) currencies, it can now handle Elecrtum seeds and encrypt them and I'm working on the intermediate code version of BIP0038. Most importantly though, although bitaddress.org is open source and is very very good (I've read it lots), it still relies on a third party web browser to display your keys, do the encryption and receive input. I know you can 'clear' a browsers cache but I know that I have never delved into a browsers code to see what it is actually doing. It seems like a weak point to my mind. Bippy doesn't need a browser so there isn't that reliance on a massively complicated bit of code written over a long time by multiple people.

Bippy will run fully offline and I totally recommend that you do just that. Boot up a Linux Live CD or USB, install bippy, encrypt your seed, write the encrypted code down and then reboot. Bippy never gets to see the internet and your seed is never exposed in a form that isn't password protected.

I do hope that Bippy becomes useful. It is a fun project and I will continue to work on it. Nico is a great guy too and it's a real pleasure being involved with something as aesthetically pleasing as wood-wallets
In answer to kuverty; A wood-wallet really is a thing of beauty. I took delivery of my first several weeks ago and I have been showing everyone since. It is wonderfully tactile and smells great. Everyone who has seen it has wanted one and 90% of them know very little about Bitcoin so it is a great conversation starter.
