Hi all!
I would like to introduce a weekend project we did with my friend Split. PaperCoin is a website that provides a very simple way for people to
print out paper offline Bitcoin wallets. Once folded, the private key is hidden inside while the address is still visible from the outside. It's a great way for introducing your friends to Bitcoin. All cryptography and PDF creation happens in Javascript
in your browser and
nothing is sent back to server. You can even download the source code (yes, it's
open source!) and run the software locally, if you wish.
Enough babbling, go to
http://papercoin.org/ and try for yourself! :-)
This is how the output page and folded wallet look like:

Feedback, ideas and patches are appreciated, of course!
