Hackerspace passports

Here’s a really cool idea: hackerspace passports. Mitch Altman, developer of the TV-B-Gone and Brain Machine, has designed a Hackerspace Passport, to provide official, non-government issued credentials to hackers, makers and time travelers visiting hackerspaces and cons throughout the solar system.
He writes:

I created Hackerspace Passports to:

-help promote people visiting as many hackerspaces around the world as possible;
-increase collaboration;
-increase cross-polination so we can all learn from one another;
-encourage all hackerspaces to support each other;
(And it’s fun.)

These Hackerspace Passports look a lot like US Passports, but no fingerprints needed! And, rather than a requirement for passing borders, they are intended to encourage it!

If each hackerspace and hacker con makes their own stamp, then people can get their Hackerspace Passport stamped everywhere they go.

Of course the design is free and open source, so the artwork is available for download from the Noisebridge site.
