Looks like hacker conventions aren't always about anarchists airing out dirty laundry: Defcon hackers are building, among other things, a camera designed to be fired out of a grenade launcher. Well, the military version is. Their version seems to be meant to use a flare gun. Like that makes it any less cool. Who knows? Maybe "Turkey and Rockets '13," the 2013 version of our annual Thanksgiving party, will be accompanied by roving miniature photography helicopters and an "eye in the sky."
