When I picked up my registration at HOPE Number Nine, a hacker conference in New York City (here are some photo of the event), I was issued this wonderful Hackers on Planet Earth Passport by the US Department of Hopeland Security. While exploring various part of the conference my passport was stamped using custom stamps for various things (here’s the stamp for the hacker favorite caffeinated carbonated beverage Club-Mate).
