Regrettably, my design partner and I decided that we cannot take place in thistoday. Time does not allow for us to put in, what we feel would be an appropriate amount of time to make it worthwhile. We did discuss over the cutting table some ideas, including the backside. One that sticks in my mind is putting a "pattern" of 'text' designed to look like the lines in a standard currency of important websites to btc as a way to advertise the community. Like I say, these were quick notions while standing over a weeding table at a print/sign shop, so they may be worthless, but as we always say, even the worst ideas can spark the best....
As I said, this will all be open. So, your design can be added to the collection at any time. In fact, I hope we will have dozens and dozens of designs in a dropdown selection, in the printing software (derived from bitaddress.org probably).
Please do stay and contribute,
Perhaps some rich bitcoin early adopter will jump in and add to the bounty - OPEN CC-BY-SA license - if anyone pays, we ALL get to use it.
Starting on Monday, the openpaperwallet will be crowdfunded on two major crowdfunding sites. Early contributors will help launch the project and will get paper wallet kits in the mail from the very first quality production run. I will also be giving bigger rewards including reseller kits from my print runs for those who want to jump start a reseller business (100 kits, ready to sell, wholesale price, shipped worldwide).
The funds raised will be used to finance the open source code, web design and many more wallet designs. So don't go away ;-)
