Grand said Moss "called me out of the blue at the end of December and he's like, 'Hey, do you want to do the DEFCON badge?' Well, it was a decent amount of time… it would've been better to be like the day after last DEFCON."

Just before DEFCON kicked off, Grand spoke with Ars about this year's badge design and the effort required to put together a real-world electronic quest for about 30,000 friends. Joe Grand, (AKA "Kingpin"), the designer of DEFCON's very first electronic, hackable badges (used for DEFCONs 14 through 18) returned to the task for this year's 27 th edition of the event at the request of DEFCON founder Jeff Moss ("Dark Tangent"). This year's badges, however, were both deceptively simple and cunningly complex, designed to get DEFCON attendees to interact with each other and explore the whole of the conference rather than falling too deeply into a badge rabbit hole. Last year's badge was a sophisticated puzzle challenge that included a social element and even a built-in text-based adventure. The DEFCON electronic badges-which for a time were used every other year because of the effort and budget that went into them-are typically the delivery vehicle for a unifying game. But the most visible, unifying part of DEFCON is its badges. And there are the Villages, each of them conferences unto themselves appealing to specific security and hacking communities.

It's the largest, of course, with over 30,000 attendees, sprawling over four hotels in Las Vegas this year. LAS VEGAS-There are many things that make the DEFCON conference stand above all other hacking conferences.
