The annual hacker convention currently underway in the Nevada desert draws a diverse crowd of professional and hobbyist security researchers from around the world. And, for the most part, they all share one defining characteristic: the desire to stick it to The Man.

Enter the Tin Foil Hat Contest. Founded by a gentleman named Flirzan, the tin-foil hat building competition was first conceived four DEF CONs ago.

"It all came out of a drunken night at the Rio," Flirzan told us. He explained that he saw an old man strolling through the casino and had a moment of inspiration: There need to be more tin-foil hats at DEF CON.
